Latest STM32-H152 board not supported by OpenOCD_0.8.0

I have a latest Olimex STM32-H152 board that has a 'Z' suffix processor.
This processor is not recognised by OpenOCD 0.8.0 (the latest release) so I cannot debug or load my firmware.

This is delaying my project considerably.
Do you know of any work-arounds to this problem?

Many thanks

I think it will be recognised if you use the right things to get it to work.  If you can get the right TAPID etc then you're good to go.

By not providing details of what you did and debug ( -d3 ) logs you're failing to give data people probably need.

Best place is bound to be the ML or site for oocd.  They will require the above.

Sorry for the delay!
This is the response I get from OpenOCD -

After talking to the FAE at Anglia it seems that the 'Z' revision of the STM32L152 fitted to the board is a pre-production evaluation revision that should not have been shipped to customers!
Hopefully someone at Olimex will look into this and make sure no-one else gets an evaluation revision processor that they cannot use!

What happens if you change the config to match what is found?

I can change the OCD script but then GDB falls over. The point is, these processors should never have got into finished items.

JohnS

gdb is some other problem.  It doesn't even know or care about the the JTAG / TAP ID etc, does it?

By way of example, you could've got those chips on a board from ST - I have had similar non-production ones on their own eval boards before now and they're fine once you tweak configs.  They have errata, as most chips have, but tend to work.

I've no idea if what you've been told is correct but I can't see why the chips can't be used OK, similar to what I've had in the past.

I make this thread up to see if something is found out about this problem.
I am in the same situation STM32_H152 and STM32L152 chip marked with a Z. I have modified the config file and now openocd starts ok. But when gdb tries to connect, then the following error happens in openocd:
Info : accepting 'gdb' connection from 3333
Warn : Cannot identify target as a STM32L family.
Error: auto_probe failed
Error: Connect failed. Consider setting up a gdb-attach event for the target to prepare target for GDB connect, or use 'gdb_memory_map disable'.
Error: attempted 'gdb' connection rejected
Is there any solution to the problem?
