JTAG on P2 connector , Debugging

Tue May 13, 2014 4:03 pm

Hi Friends ,

I am trying to access RPI through 2nd JTAG on P2 ( not through P1 which need to be chnaged as JTAG ).
I am using OpenOCD with OLIMEX ARM-USB-OCD-H .

I get following error ...

"Info : only one transport option; autoselect 'jtag'
adapter speed: 1000 kHz
none separate
bcm2835.arm
Info : clock speed 1000 kHz
Info : JTAG tap: bcm2835.arm tap/device found: 0x4270817f (mfg: 0x0bf,
part: 0x2708, ver: 0x4)
Error: IR capture error at bit 5, saw 0x01 not 0x...3 Warn : Bypassing JTAG setup events due to errors
Error: 'arm11 target' JTAG error SCREG OUT 0x00
Error: unexpected ARM11 ID code "

Has anybody tried using direct JTAG on P2 before . KIndly help !

Thanks
Sunil
