This happens on bf537-stamp and bf533-stamp.

--- Cliff Cai 2010-06-10 05:28:28

crc error was ocurring during the test.

--- Cliff Cai 2010-06-30 02:50:44

After some investigation,I found that some patches are related to this bug:

1.r7862 | jiez | 2009-11-24 22:59:10 +0800 (Tue, 24 Nov 2009) | 4 lines

Fix bug [#5706].

Restore my fix which was lost during updating to linux-2.6.30.

Flush icache when write to user process space.

2.r7871 | vapier | 2009-11-25 13:39:03 +0800 (Wed, 25 Nov 2009) | 1 line

Blackfin: drop ptrace() write support for fixed code/bootrom -- we dont want to

let people to write to these regions

3.reverting above two patches can make the test work until the kernel was

upgraded to 2.6.32 at revision 7916.This kernel upgrade almost didn't change the

code of ".../drivers/mmc/host/mmc_spi.c" and

".../drivers/spi/spi_bf5xx.c" ,So,the problem must locate elsewhere.

those code paths shouldnt matter as they only get executed when running things

through ptrace (i.e. gdbserver). this test case isnt executing gdb i dont

think, so those changes shouldnt make a difference to it.

--- Sonic Zhang 2010-07-08 22:38:41

The bonne++ always fails in the middle of a multi block MMC SPI writing

operation. A CRC error is reported by SD card for one of the blocks it received.

It looks the SPI bus is not as reliable as the MMC SPI driver expected. Accident

bit error when transferring large continuous data over SPI bus can't be avoid.

Current solution is to redo data writing command in mmc spi driver when CRC

error is perceived other than fail the operation immediately. The retry count is

set to 5, which ensures no failure in overnight stress test.

--- Sonic Zhang 2010-07-09 04:07:33

Fixed.

--- Vivi Li 2010-07-13 01:09:13

It's OK now.

Close it.
