Summary: dd bfin-otp device with big count has Input/output error

Details:

dd bfin-otp device with big count has Input/output error on bf548 ezkit.

if use count number bigger than 3, it would repot failure. but it used to be 440 in March 13 last pass testing.

Follow-ups

--- Mike Frysinger 2009-05-19 05:05:22

are you using the exact same board ? OTP will differ according to the part.

another possibility is that some OTP fuse actually blew causing an ECC failure.

nothing can be done in software to work around that.

you should enable debugging in the bfin-otp.c driver (add '#define DEBUG' to

the top of it) and then re-run your test and post the output of `dmesg` after

doing so.

--- Mingquan Pan 2009-05-19 05:59:52

Yeah, it could be two boards. And I enable the debug info, it says:

root:/> dd if=/dev/bfin-otp of=otp_out.bin0 bs=8 count=440

dd: /dev/bfin-otp: Input/output error

0x11 is OTP_DATA_MULT_ERROR which means the page data is unrecoverable. nothing

to be done in software -- the driver is operating correctly afaict.

--- Mingquan Pan 2009-05-19 22:21:01

So I use the small value to test and close this.

--- Mingquan Pan 2009-06-02 04:11:07

I open this to have one more question found on two bf527 ezkit boards with 0.2

But I still feel strange, these two boards are quite new, if they are fail, so

the case fail with bf527 ezkit.

Is it possible that there are some jumper need to set?

--- Mike Frysinger 2009-06-02 04:21:09

i'm pretty sure there are no jumpers. OTP is all internal to the part and there

is no external access to it.

the first 4 pages are protection bits, so any bad programming in the rest of

the OTP region could cause problems there.

you can use u-boot to double check things. the interface is a bit more compact

and easier to use:

bfin> otp read 0 0 16

one test you should be able to do is read page 7 -- it'll be an ascii string

representing the part you're running on followed by an ID for the variant:

bfin> otp read 0 7 2

OTP memory read: addr 0x00000000 page 0x007 count 2 ... .. done

bfin> md.b 0

00000000: 41 44 53 50 2d 42 46 35 34 39 00 00 00 00 25 02 ADSP-BF549....%.

0x0225 == BF549

--- Mingquan Pan 2009-06-02 23:08:59

On one of the bf527 board ,I run above command in uboot:

--- Mike Frysinger 2009-06-03 03:29:01

that first read command shows that there is an unrecoverable error in the first

page. nothing i can do about that. i'd suggest you adjust your script to read

page 7 and check those values.

--- Mingquan Pan 2009-06-03 05:02:27

How can I specify to use page 7 ? I only operate on device /dev/bfin-otp.

--- Mike Frysinger 2009-06-03 05:07:00

use the skip= option with dd to ignore the first few pages. one page is 128bits

(or 16 bytes).

--- Mingquan Pan 2009-06-03 06:27:24

Yes, it can dd right now on bf527 ezkit.
