Hi Im trying to get the JTAG working on the Autonomo and what tools.
I was wondering if anybody else has tried this - or any hints.
I have two Autonomo Rev5 recently purchased with 10pinJ1 (thankyou thankyou).
I’ve started with the BlackMagic Probe (but also have a MultiLink Universal, NXP LPC-Link2 …)
I plugin the JTAG cable and then BlackMagic USB which enumerates successfully.
Then plugin the Autonomo USB to power it.
I start in platformio/VisualStudio and in the terminal bring up
C:\Users\ user\ .platformio\packages\toolchain-gccarmnoneeabi\bin\arm-none-eabi-gdb.exe
GNU gdb (GNU Tools for ARM Embedded Processors) 220.127.116.1160923-cvs
(gdb) target extended-remote COM8
(gdb) monitor version
Black Magic Probe (Firmware v1.6) (Hardware Version 3)
(gdb) monitor jtag_scan
Target voltage: 3.3V
JTAG device scan failed!
I could only find the Rev3 schematic - https://support.sodaq.com/sodaq-one/autonomо/schema/
but it looks like it should suppport JTAG.
