The AT91SAM9260 appears to include EBI support for CompactFlash, but the AT91SAM9260-EK development board does not include a CompactFlash interface. Assuming I can come up with the hardware, how hard will it be to develop the U-Boot and Linux driver support required to boot Linux 2.6 from CompactFlash on the AT91SAM9260? Is this driver code already out there somewhere? Thanks. Jim ...

Hi group I heard rumors that's possible to read out how many times a given CompactFlash was written to. I haven't found out how to get this information out of a card yet. Does someone know ? TIA Markus

I want ask which mode is using CompactFlash device. It's not clear from ATAPI-4 spec. Is it always PIO in/out protocol or can I even run write/read in any of DMA modes?

I have an 8051 uC using a CompactFlash. Using LBA I know how to open in read or write mode in a specific sector. I'm needing to find out if its possible to access a specific byte without re-writing data. If so, how? Thanks, Sean

Hello, I wanted to inquire if someone else has seen this kind of phenomenon before... I have a design (currently implemented in an FPGA) which drives a CompactFlash from a microcontroller, specifically a T80 (Z80 clone) from opencores.org, with my own firmware. The clock frequency is 25 MHz. The weird part is that it reads all cards fine, but when it comes to writing I get some extr...

Hello, We are developing a Linux based embedded system that will use CompactFlash. Should we prefer ext2 or ext3? How should we think about the trade- offs? What is your experience using either in a fielded system? Thanks. Jim

Hi, I am trying to write a program in C language to format a Compact Flash card. I have the CompactFlash Association specification. I am unable to figure out how to read and write to the flash card and configure the various registers to support memory mode. If anybody could give me some tips or sources of information, it will be very helpful. With Regards, Anupama.

am converting an old laptop into a digital picture frame. My thought was to create a small XP (nlite) with the apps I need (slideshow, wireless, vnc) on a hard drive and then copy it over to a CompactFlash which I would then replace the laptop harddrive with. I've got a nice tight version on a hard drive (under 500Mb) ready to put onto CF. Problem: it doesn't appear that the BIOS I have wi...

I have managed to access a Sandisk CompactFlash device using an 8051 micro, and am able to read its identity, and also read and write sectors in this device. Next task is to tackle FAT16... My question relates to the Identify command (0xEC) with which one can check out the CF device's intrinsic parameters. Does one always have to use this command to electronically determine what the capac...

I've done an ATA IDENTIFY on several high speed CompactFlash devices, using True-IDE mode, and none of them report any DMA capability at all. This is a bit worrying. (ie, 2GB Lexar Media drives for example) The CFA 3.0 spec is confusing in this regard. Sometimes it says that DMA modes are supported, but at other times other times there are implications that DMA is not supported. For ins...

[ Message cross-posted to comp.arch.embedded and comp.arch.storage ] Hello everyone, I have an x86-based system running Linux, and I'm considering using a CompactFlash card for non-volatile storage, instead of a typical hard disk drive. I was wondering if I could just use the same IDE driver I've been using for hard disk drives. As far as I understand, if I use a CF-to-IDE adapte...

I'm trying to find out how to read the manufacturer and product name from the 'Card Information Structure' on a CompactFlash card. Here's the details: - Linux 2.4 kernel - BusyBox v1.00-rc3 - Need to be able to read the CIS from userland - Need to be able to read the CIS from an embedded C++ application (in other words, not by viewing 'dmesg') - Linux is running from the CompactFlas...

I'm contemplating replacing an old ATA hard disc with a CompactFlash card in an adaptor. I've been reading the CF 2 specification, which suggests that /CSEL is used to select between master and slave mode (grounded=master, open=slave). So if I use an adaptor I should be able to put a CF card and another IDE device on the same bus. In theory. But knowing that True IDE isn't well tested, ...

Hi all, Is anybody knows how to configure CompactFlash for best performance. What register ? May be FEATURE_REG in ATA's ? My design reaches about 150Ko/s which is far from CF spec. Thank you all, Habib.

Is it always, infallibly, 100% true that a disk sector is entirely contained within a single partition? If it matters, I'm concerned about ext3 partitions on a CompactFlash card. Thanks, Adam

I'm trying to find some code for my CompactFlash project. All the code I find is for AVR and obviously wont work. Does anyone have any full code I can have? OR can recommend a place to purchase code? Most of the code I have found for sell is for x86 boards. Thanks, Sean
