Hi,

Hi,

I had the same issue when I tried RPi 3 with OpenOCD.

There are my experiments:

# RPi 3B V1.2:

Linux raspberrypi 4.9.41-v7+ #1023 SMP Tue Aug 8 16:00:15 BST 2017 armv7l GNU/Linux
Hardware : BCM2835
Revision : a22082

#OpenOCD 0.10.0 [2018-11-30] download at: http://gnutoolchains.com/arm-eabi/openocd/

#ARM-USB-TINY-H adapter

I changed in the JtagEnable.cpp file as #define BCM2708_PERI_BASE 0x3F000000

However when I run this command: <Directory Path>\OpenOCD-20181130\share\openocd\scripts>..\..\..\bin\openocd.exe -f interface\ftdi\olimex-arm-usb-tiny-h.cfg -f target\raspberrypi3.cfg

There were errors as bellow:

I have double checked my wiring between RPi 3 and Olimex.

Would you please help me in this case? Thank you  so much.
