Indicator for long time flashes and counter windows remain in 00000 and nothing done,please help me what do i?in attachment i show printscreen of system is pentium 5 and windows 98. Best (...)
Considering that most I2C memory devices are able to deal with clocks up to 400 Kbps, perhaps this will be an issue to the PIC to "read-from-there-and-send-to-converter", particularly if you chose a high quality audio, i.e at 20 KHz. I'm not sure if the complete reading cycle of the I2C protocol spend more than 40 clocks ( 400K/20K ), but unless yo
Could you advice any file system to include in our project for IoT application? I hope that somebody on this forum had faced the similar problems. We are looking for solution allows to make three function: write, read, erase. The system should works fast and be insensitive to power failures. Firstly, we tried to use Coffee (...)
Hi everybody!! How can we read USB flash or other peripheral from PL side directly (does not involve CPU or DDR)on Zynq SoC? Can we use usb2.0 IP in this situation and what about file system?
to read/write file on flash you are going to need a file system. so you are going to implement a nios2 capable to load a file system code that will allow you to open,read and write files.
Currently, I have designed a second-order Sigma-delta ADC (fin = 20kHz, fs = 5MHz). In this ADC, a 2-bit flash ADC was adopted as a quantizer, and a 2-bit DAC was inserted into the feedback signal path. The attached file is the system architecture and the simulated results. 113250 According to the output spectrum of th

Hi all, I am working on SD card with LPC2148 in RTX-flash system, i am using NEX-robotics board it communicate via SPI0 but the RTX uses SSP in demo codes. I have changed the demo coding to SPI0 for the configuration, I have attached my changed file and original demo code with this. Can anyone did the SD interface with LPC2148 in RTX mean
Hello All I am using Keil - RL-flash FS to interface with SD-Card. I am having in difficulties with the configuration and Initialization of the card. Once I call the Init_Card(); the Uart Stops responding. I am not able to read or create a file. I dont know what I do is right or wrong. I am posting the project here. Please advise on this. Pleas
Hello, I am trying to implement a system that saves the FPGA configuration data to 2 flash PROMs (xcf04s) connected in Master Serial Mode to the FPGA (Spartan 3E 1200). What I have done so far 1. I have designed a simple test VHDL entity, verified its working. 2. I have configured the PROM with the bit stream by creating a
Are you writing through a file system or logical sectors directly? Is the SDCard (mostly) erased before writing data? Generally, the delay is most likely caused by internal housekeeping actions of the flash translation layer. It requires that from time to time physical blocks have to be erased and copied. Consider that the smallest write (...)
Hi, I have a query on deciding USB flash requirement. Is there a relation between USB controller(in Processor) and the Pen drive size that can be connected? Basically,if i have a USB host controller integrated in my processor,will i be able to connect a PEN drive of any size? Or are there any practical limitation? Regards, VJ
Hi....... I am implementing USB mass storage implementation on STM32. I have used on chip flash memory as mass storage. when i plug the is detected by PC(windows)... but is not formatted...i have only 256KB flash memory..which file system to be used for this small volume....
Hello! EEPROM or whatever external flash can store whatever you feed to it. You can even create a file system on one flash chip and make your PC believe it's an external USB memory. Well, you cannot do this with 8051, I guess. But at least you can program your external memory. Dora.
Possibly. I've personal only used the FTP Protocol to transfer a file. Have you implemented SD or MSD flash Card storage? BigDog
but that's not a typical spi flash controller,just 12 instructions do you need more? What are you exactly missing?
Hi, I am trying to interface LPC2138 with micrSD card(2-GB). I picked up the demo code for LPC2148 based on flash file system(since LPC2138 is almost the same as LPC2148 except for usb device peripheral). On running the code: I can see the menu on UART(uart is working fine). But it gives error: " MMC/SD card init failed.. Insert Card (...)
you can program it with serial port.. there is no need of an programmer.. connect controller UART to pc. use flash magic or anysoftware and download the hex file directly, without any programmer.......
dear all Can anyone tell me how I can load an image file like .tif on to the system ace compact flash embedded on virtex 2 Pro30 kit? also how i can make compact flash as storage area (for data) not for configure FPGA? wait your reply regards

Hi, I am working on an embedded hardware which has a pxa255 processor with AMD's AM29LV256M flash chip. The system acquires analog input, passes thru the ADC, after processing, stores the data in flash memory. However, sometimes the data is corrupted when writing to the memory. I checked the timing and the voltage levels of the lines and (...)
well, how much memory do you want? maybe a serial eeprom (24Cxxx) or serial flash(SST25VF016B for 2Mbytes!!!) could be enough for your app.... remember, mmc & SD haw lots of memory (up to GB), but if you want to interact with data already stored there, or want your data accessible on PC, you must implement a FAT file system... if (...)

Hi all, I have one question about friendlyarm mini2440.Can we download rootfile systems of more than RAM sizes into nand flash? and How? thnks in advance.
Dear All, Anybody ever tried to use SD card with the flash file system? (TFAT, JFFS, JFFS2, UBIFS, etc). Any idea on which is best? and how to make a database/file system with SD? Kindest Regards, FE
Hi, use a uC, which provide a USB and flash interface. then use the USB connector, USB phy for PC/laptop interface. on other hand, use a array of flash .. create a file system in uC to access the particular flash... job
Hi, i need design a system to read file that store in CF card by using PIC, can anyone introduce any note or site that got teach how to develop the software or requirement? i have read some related note but still not enough info for me to do the programming..thanks for any advice..
hi, if you want to make stand alone system then in your smart design you have to instanciate coreNvm and you have to connect it at 0slot of Ahb or AhbLite whatever you have used. After that you have to inintialize nvm form catlog window -> flash memory systembuilder -> initalize . Here you have to import hex file (...)
we have our system design that will produce sound from zero to nine and then we will using xilinx spartan 3E for this design. . .this sound file is a downloaded wave files but our problem is we don't know where our wave files can be stored within the spartan 3E board. . .can we use the Intel Strataflash (...)
One of the earlier flash cards was MMC. This was later replaced by SD cards. Both of these could be read in SPI mode. With this info, I would suggest attempting to wire one of these devices to an SD adapter and try a standard USB card reader. This may work, if the device has something resembling a file system on it. If the device is (...)
Need Reference design of Pic MC+Nanad flash file system ,Any one have that One?
You could create a software that converts the pps file into several jpeg image slides and store in a USB as it will not require a an OS. Added after 3 minutes: Wouldn't it be easier to use linux on flash instead of windows. You can use openoffice to read the pps files and you can also slimline the OS to you
Hello, check the JFFS2 Journalling flash file system 2 which is widely used in embedded systems. Regards Mowgli
or use simple state machine and flash ROM attached through CPLD to your AVR
Take a look to Atmel application notes In-system Programming with C51 MCU and External flash . In "flash.c" file you can find all the functions that you need.

Hello, Does anyone know what the ACE Compact flash Controller just does? Thx!
hi all, My project needs mass storage, and i decided to use a device for this purpose which should be carried in pocket. And i heared about COMPACT flash. Did any one used it. Actually it follows FAT file system. I got very good idea about how to use the compact flash and how files are begin (...)
hi, in a project which requires to download ,say, an Audio file from PC to a flash card.. and then playback independently..... FAT is a simple but v.bad way to go But if JFFS2 is far as the device is connected to LinuxPC then there are no problems.. but.... how easy or hard is it / and what effort it takes: -> to read th
I don't see how the OS can be damaged if there is a loss of power. You can have data los of corruption in the file system only. But if you are using some of the journaling file systems like ext3 you should be fine, after reboot, system will restore filesystem in the state (...)
Hello everybody, I´d like to save some files on my hms720´s flash. So I start to mount jffs: mount /mnt/jffs Then I create/copy a file on this file system. It stores proper for files <= 11 byte. For files > 11 byte I get an segmentation fault and a mem dump. Can (...)
Sounds like you want to read/write an MMC card's flash file system using using a PIC controller. I believe it uses a FAT12 or FAT16 file system. Maybe this SanDisk doc will get you started: I think these guys produced the official spec, but it's probably expensive:
For 32 bit CPUs look Micromonitor by Mr. Ed Sutter: MicroMonitor is an embedded system boot platform centered around an extensible embedded flash file system called TFS. With TFS in the monitor, things like XMODEM and TFTP (also in the monitor) can now refer to files instead of address space.
I have an embedded design based in a Power PC and a massive storage device is needed. I have found a SAMSUNG NAND flash device fitting my requirements but the problem I need to solve is how to interface between the file system from the Operating system running in the microprocessor and the flash device. (...)
Hello, I want to use 51 to control flash, but as you know 51 Address bus is surely less than flash's address, so i insert a fpga between, but shall I use file system like FAT16? I don't like the complex file system, but how about the other ways? Waiting for your suggestions! (...)
I don't use PROMGen (it creates the MCS file). Instead, I run BitGen with the "-g binary:yes" option. That produces a BIN file containing the pure binary bitstream without any headers or other junk. I link that BIN file into the rest of my project, which gets burned into flash, and then executed by a DSP (...)
