[En-Nut-Discussion] problems making binairy to burn in flash

[Ulrich Prinz]

Hi!

Did you try to flash by starting oocd and using the telnet code?
Another thing is, that I found some older versions of oocd that use some 
not so correct register setups for the SAM7X-EK platform. They setup PLL 
for 16 or 12MHz chrystals but on the EK a 14.xxMHz is mounted.

I recommend to use oocd version 0.1.0 or 0.2.0. Both work fine with my 
integration of the make burn in the trunk of nutos. Select arm-oocd 
instead of arm-jom.

The scripts have a small problem I could'nt solve. I didn't manage to 
find out the CPU the binary is compiled for. So the scripts under
tools/scripts/flash-entry.script and flash-exit.script are fixed to 
SAM7X256 so you might have to exchange that.

I tested the scripts with SAM7X-EK and the SAM7S based EIR and they are 
working quite good with oocd 0.1.0 and nearly perfect with oocd 0.2.0 
and the upenocd-usb dongle.
If you have another dongle, you need to adjust Makeburn.oocd

For testing it might be easier to put the commands by hand via telnet 
instead of modify script, run make burn, fail, and again. So call
openocd -f interface/yourif.cfg -f target/sam7x256.cfg -c init
and telnet to localhost:4444
Then try giving the commands from flash-entry, that flashing part from 
Makeburn.oocd and flash-exit.script by hand.

Hope it helps.
