RE: when port a software , bus error

Zhenfeng, As Sid pointed out, the bus error is due to access of int32 data at non word aligned address. You have turned on structure packing with the #pragma directive. If this was not done, the compiler would have padded 3 bytes between the char 'm' and int 'data'. In that case, the int 'dat

RE: when port a software , bus error

Hi, On Arm, you can access only word aligned data. To access a 32 bit value, the address needs to be 32 bit aligned etc.. If the data is not aligned, then a bus error is thrown. I'm guessing that its because of the char m, data[] will not be aligned in _test_c. Thanks and Regards, Sid +91-80

Re: Changing Machine ID

Hi, AFAIK, the appropriate machine ID is selected at the time of compiling the available source code. If you are using the available makefile directly, then I suggest you go for recompilation with the appropriate machine ID option set ( - M i think) and enter your own machine ID. That will p

DSPLINK: MSGQ_get() with WAIT_NONE arg causes freeze

I am having trouble getting MSGQ_get() to work when set to non-blocking, i.e. with the parameter "WAIT_NONE". It works fine blocking. I am using dsplink 1.60, and testing on the DM6446 EVM. The symptom of the problem is the Linux OS freezes, requiring a reboot. I have isolated the problem with

U-Boot and CONFIG_SYS_DAVINCI_BROKEN_ECC

I was looking at the DaVinci NAND support in current U-Boot code (i.e. 2009.03 plus patches merged since that release), and am puzzled by the above-named config option. Before I submit a patch to remove it from U-Boot GIT (nothing there enables it, and it will nastify 4-bit support), I thought I'd
