Thank you a lot Antonio for the information, I have to find an alternative
debugger then.

** [tickets:#280] stlink-v2 not working with bcm2835 raspberry pi**
**Status:** new
**Milestone:** 0.9.0

Hi:
I am trying to use a stlink-v2 to debug a raspberry pi (bcm2835) using jtag,
but I am not succeding. I have tryied with two transports, hla and dapdirect,
and each of them is giving me different problems.
Using the openocd snapshot from debian unstable (from 2020-08-19). The commands
I use to connect and the debug output from openocd are the following:
- Using hla:
$ openocd -d3 -f interface/stlink-v2.cfg -c "transport select hla_jtag" -c
"adapter speed 100" -c "hla newtap raspi arm -irlen 5 -expected-id 0x07b7617F"
-c "target create raspi.arm arm11 -chain-position raspi.arm"

As you can see, the hla transport seems to not support arm11 as target. On the
other hand, the dapdirect transport seems to ignore the -irlen flag passed to
the jtag newtap command, and then the openocd complains when the tap is
initialized.
Can anyone help me to solve this problem or at least throw some light on it?
Have anyone succed in using stlink-v2 to debug a raspberry pi using the jtag
protocol?
Thank you all.
Christian.
