Hi Blair,

some data structure has been updated, maybe you need make clean the icc_utils directory and try it again.

Hey Steve,

Did not seem to help,

If I follow the instructions here...

docs.blackfin.uclinux.org/doku.php?id=test_mcapi_on_bf561

From my understanding, it is not recomended to do a ./configure from within any distrubution.

When I do I get, the expected message, do a make distclean

I selected to build the libmcapi from within the uClinux menu.

Also I am getting this error when trying to compile libmcapi

checking for size_t... (cached) yes

checking for uint8_t... yes

checking for uint16_t... yes

checking for uint32_t... yes

checking for uint64_t... yes

config.status: creating Makefile

Hey,

I install libtools and ran ./autogen.sh it created the missing file "config.h.in"

Now it compiles...

Hey,

I am still having the original issue and cannot seem to get a test to work.

This exception is being raised, this is the code in "corebboot.c"

void dump_execption(unsigned int errno, unsigned int addr)

{

coreb_msg("execption %x addr %x\n", errno, addr);

}

Thanks,

Blair

Hi,

I managed to narrow where the exception is being thrown.

It is in file protocol.c and the function

void sm_handle_control_message(sm_uint32_t cpu)

Line Number 393

memcpy(&sm_task1, msg->payload,

sizeof(struct sm_task));

It would be nice to know why memcpy is causing this????

Hi Blair,

yes, it's probably cause by sm_task structure change, can you go to uclinux-dist/blkfin-app/icc_utils/icc_loader, run make clean and make to update the icc_loader.

btw, do you configure the bootargs for icc test, can you list your /proc/cmdline after bootup

Hey Steve,

Thanks for getting back to me on this,

I am working with a custom board, it has 128Megs on it so I was setting the bootargs so the last 4Megs was reserved for coreb task buffer.

mem=124M max_mem=128M.

As you know this was not working, then I set it to the following and now it works.

root:/bin>

root:/bin> cat /proc/cmdline

root=/dev/mtdblock0 rw clkin_hz=30000000 earlyprintk=serial,uart0,57600 console=

ttyBF0,57600 mem=60M max_mem=64M

root:/bin>

What needs to be done to use the whole 128Megs???

Hi Blair,

currently the COREB addree hard code to 64M memory size. if you want to use last 4M of 128M ram, i think you can modify the uclinux-dist/linux-2.6.x/arch/blackfin/mach-bf561/include/mach/icc.h, define the COREB_TASK_START to 0x7C00000 and COREB_MEMPOOL_START 0x3D00000
