Problem accessing Sandisk CompactFlash Cards (Connected to the IDE bus)

Hello all,

Iam running an embedded system out of Compactflash. Kernel version is 
2.4.27 (happens with all version i tried, 2.4.21-2.4.27).
The system is in use for a few month already, but i started to 
experience problems with a newer revision of the Compactflash Cards from 
Sandisk, when reading or writing to the device data gets corrupted and 
the following message is written to the logfiles:

hdb: drive not ready for command
hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }

hdb: drive not ready for command
hdb: irq timeout: status=0xd0 { Busy }

ide0: reset: master: error (0x0a?)


I tried setting a longer WAIT_DRQ timeout in ide.h, but that doesnt 
solve the problem (even with really large values, about 10 times the 
default).
One thing which is interesting about the new card is that it isnt 
detected by the kernel as a CFA device, but just a regular ATA device.

I attached the output of hdparm -I for both cards if that helps.
The IDE controller is a VIA VT82C586A/B/VT82C686/A/B/VT823x/A/C 
(according to /proc/pci).
lspci -vv output is attached too.

Thanks in Advance for any suggestions to this problem.

Its been awhile, but the last time that I looked at the relevant code, 
there was a table of drive vendor/device strings that were used to 
identify CFA devices and differentiate them from regular ide devices.  
If this particular device isn't a match in that table, it would be 
mis-identified, and that could be leading to your above problem.

Thx for the suggestion. The only table i could find is in 
drive_is_flashcard, which is only checked if drive->removable is set, 
which is not the case with the newer card (but is with the old one).
Another thing which is weird is that the old card returns an id->config 
value of 0x848a which according to manuals from SanDisk is for a 
Compactflash card NOT running in True Ide mode, but instead in memory 
mapped IO mode (iam no expert for Compactflash, so i dont even know the 
exact difference), but as far as i can tell are both cards wired by the 
IDE adapter so that they should run in True IDE mode, and if i 
understand the Compactflash specification correctly, this is the only 
mode of operation which is electrically compatible with the IDE/ATA bus, 
isnt it?
I tried forcing both the drive->removable and drive->is_flash flags to 
the true, my dmesg output then shows me the card as a CFA DISK drive, 
but i still get the same errors when reading or writing from/to the device.

TIA for any further hints,
Marc

What kernel are you looking at?  I'm looking at 2.4.21, and it seems to 
get checked more-or-less universally.  Also, I noticed this:
|| !strncmp(id->model, "SunDisk SDCFB", 13)    /* SunDisk */
I've not heard of SunDisk.  SunDisk->SanDisk == Typo?
Are you using a SanDisk CFA card?  Could this perhaps be part of your issue?

Indeed this is a typo but has been fixed on 2.4.26:

        if (drive->removable && id != NULL) {
                if (id->config == 0x848a) return 1;     /* CompactFlash */
                if (!strncmp(id->model, "KODAK ATA_FLASH", 15)  /* Kodak */
                 || !strncmp(id->model, "Hitachi CV", 10)       /* Hitachi */
                 || !strncmp(id->model, "SunDisk SDCFB", 13)    /* old SanDisk */
                 || !strncmp(id->model, "SanDisk SDCFB", 13)    /* SanDisk */
                 || !strncmp(id->model, "HAGIWARA HPC", 12)     /* Hagiwara */
                 || !strncmp(id->model, "LEXAR ATA_FLASH", 15)  /* Lexar */
                 || !strncmp(id->model, "ATA_FLASH", 9))        /* Simple Tech */
                {

I haven't got much of a clue about IDE, but I can see the newer card supports
DMA, and the older doesnt, but you are probably not using DMA on that? whats
the output of "hdparm /dev/hda".

Also can you show us dmesg from both old and new cards.

It never gets past this check because drive->removable is not set!

Ive attached the hdparm output, which is exactly the same for both cards.

I've noticed another interesting thing, when doing the same stuff which 
bails out on the new card (reading or writing larger amounts of data), 
sometimes with the old card a kernel message "VFS: Disk change detected 
on device 03:00" appears in the logfiles, which doesnt appear with the 
new card.

Also attached are the both dmesg outputs from booting up and the 
occurence of the error, respectively the disk change event. This logs 
are from an Adeos/Rtai patched kernel, but the exact same problem 
appears when booting with a stock 2.4.27 kernel to.

Theres actually a more interesting difference to notice:

In the working dmesg output I see this:
 > hda: SanDisk SDCFB-128, CFA DISK drive

While in the non working dmesg output we have:
 > hdb: SanDisk SDCFB-128, ATA DISK drive

Tracing back through the code it looks to me like we get the ATA disk 
print in the event that this test in do_identify:
/*
  * Check for an ATAPI device
  */
  if (cmd == WIN_PIDENTIFY) {

that would explain why the drive_is_flashcard test is getting skipped, 
why setting removable is making no difference, and why your card is 
being identified as an ATA device.  It looks as though the WIN_PIDENTIFY 
command is sent down to this routine from ide_probe_for_drive in this 
snip of code:

/* if !(success||timed-out) */
                 if (do_probe(drive, WIN_IDENTIFY) >= 2) {
                         /* look for ATAPI device */
                         (void) do_probe(drive, WIN_PIDENTIFY);
                 }

So it would seem that WIN_PIDENTIFY is issued only if a WIN_IDENTIFY 
command fails with an rc greater than 2.  I would suggest instrumenting 
this area of the code to see what the WIN_IDENTIFY command is returning 
on the working and non-working systems.  I'm betting you will find a 
difference, and we'll be able to track down the problem from there.

Both Cards, the old and the new on dont get to the ATAPI probing (which 
seems correct to me, or is compactflash an ATAPI device???)


>

WIN_IDENTIFY returns a rc of 0 (for success) with both the old and the 
new card. Still the old ones gets detected as CFA!


One thing i did notice when tracing these functions, is that the new 
card returns 0x44a in drive->id->config, while the old one returns 
0x848a, according to the manual from 
SanDisk(http://www.sandisk.com/pdf/industrial/ProdManualIndustrialGradeATAv2.6.pdf) 
Should only be returned in memory mapped(cardbus/pc-card) mode, and not 
in True IDE mode, which the card is appearently running, otherwise the 
bios couldnt not boot from it, nor would the electrical interface be 
compatible (if i get the manual right). That is imo why hdparm -I doesnt 
detect the card as beein removable and Compactflash too, i looked as the 
sourcode of hdparm, and it seems to read the ATA configuration registers 
trough a proc file, and interpret it directly (without intervention of 
the kernel).
So the data the does return indeed marks it as an ATA harddisk, and not 
as a compactflash card, the real question then is why doesnt it work as 
a harddisk, which according to the specifications it should? Iam not 
really experienced in the ide stuff, so iam not sure what the 
CompactFlash detection in linux changes in behaviour.
I can get the kernel to report it as a "CFA DISK Drive" in dmesg by 
forcing the flags i mentioned before, but the error is exactly the same.

Thx for your help,
Marc

CF cards in IDE mode appear as ATA disk not ATAPI

It basically changes the removable drive behaviour. It could
also be useful for knowing when we need to be careful as
CF cards are both fragile and have some different commands.

What is the CF card connected to. One possibility is that
something after boot is powering the CF card off and on or
switching its mode before we see it.

Sorry, I've been mixed up here.  I've been focused on the removable flag 
aspect of this problem.  To level set here:

1) older SanDisk cards are detected as CFA devices and are working, but 
not bootable.

2) newer SanDisk cards are detected as ATA disks, and are bootable as 
such, but do not seem to be operating correctly (the aforementioned ide 
errors).


Is this correct?

The first question to answer is, which mode do you want to operate in? 
(I assume True IDE is what you're after, but just to be sure). 
According to the Manual you provided the link to, CFA cards select which 
mode the operate in (CFA or ATA) from poweron based on a sampling of pin 
0x0E. on the physical interface (from section 3.7 on page 43).   So it 
seems you have two supposedly identical pieces of hardware that are 
configuring themselves from poweron in opposing ways based on the 
electrical characteristics of the same bus pin.  If this is correct, 
then I would be forced to conclude:

a) the state of that bus pin is fluctuating.
b) the CompactFlash cards that you have treat that pin differently

Either way, it seems that you have two cards which should be, but are 
not getting detected/configured in the same way.  That would somewhat 
suggest to me electrical issues on your bus, which may account for the 
ide errors you are seeing.

Not fully, actually both are bootable, but the second one gets 
read/write errors after booting, and when accessed after booting from 
another boot device (NFS)

for the other points, actually both cards are used in the same adapter 
hardware. I can switch both cards in ONE system, and the error only 
appears with the newer card.

I found some other subtlety, in the dmesg of the nonworking card there 
is a message:

hdb: C/H/S=0/0/0 from BIOS ignored

which doesnt appear with the working card, so the card is already 
treated differently by the bios, or the different information from the 
bios somehow interfers with hardware probing? (just speculating on this 
point)
I will do some more tests and tell you what i find out.

Nope. It was called SunDisk at first but then Sun told them to change
their name and they changed it to SanDisk. There a CF disks with both
names in the wild. But there's no problem, recent kernels (both 2.4 and
2.6) recognize both names as CFA.
