[OpenOCD-user] Program Kinetis K70 via J-Link

[Gaëtan C. <gc...@gm...>]

Hello,
I have problems when trying to flash the TWRK70F120M board from 
Freescale using J-Link probe with OpenOCD version 0.9.0-dev-00131-gbd0409a.

Here is my script:

$ openocd -d0 \
-f interface/jlink.cfg \
-c "transport select jtag" \
-f board/twr-k60f120m.cfg \
-c "adapter_khz 400" \
-c init \
-c "reset init" \
-c "reset halt" \
-c "sleep 500" \
-c "flash probe 0" \
-c "kinetis mdm mass_erase 0" \
-c "reset halt" \
-c "sleep 500" \
-c "flash write_bank 0 app.bin 0" \
-c "reset halt" \
-c "verify_image app.bin 0"

And the when verifying (very slow), i have this error (full log at the end):
...
wrote 524288 bytes from file app.bin to flash bank 0 at offset 
0x00000000 in 21.998293s (23.275 KiB/s)
Error: timed out while waiting for target halted
target state: halted
target halted due to debug-request, current mode: Thread
xPSR: 0xa1000000 pc: 0x0000511c psp: 0x1fff4bf8
Error: error executing cortex_m crc algorithm
verified 524288 bytes in 65.222839s (7.850 KiB/s)
...

If I shutdown script just after "flash write" command, board stay 
halted. But when verify_image command is issued/started, the board is 
reset and application is runinng until "Error: timed out" appears.
Even with a "reset halt" after "flash write" command, the error occurs.

I used the patched version of k60.cfg with SRAM area enabled 
(http://openocd.zylin.com/2277)

Thank you for your help,
Regards,
Gaëtan Carlier.
