Hi,
I want to use openocd to reflash PXA270 board (Colibri by Toradex). I am
using JTAGKey-Tiny interface (by Amontec). I can connect the board but I
always get the error message:
'time out writing RX register'. Here is the output for 'reset' and
'flash info 0':
> reset
JTAG tap: pxa270.cpu tap/device found: 0x79265013 (mfg: 0x009, part:
0x9265, ver: 0x7)
Failed to receiving data from debug handler after 1000 attempts
time out writing RX register
> flash info 0
time out writing RX register
Command handler execution failed
in procedure 'flash' called at file "command.c", line 650
called at file "command.c", line 361
>
Attached you will find my config files.
Thank you for your help!
Best regards,
Áron
