Problem with P&E Micro USB Multilink

venca — Tue, 17 Jun 2008 16:52:49 GMT

Hi,

I'm working on a project using MC 13213 and P&E Micro USB Multilink. Recently I have installed a new CodeWarrior version 6.2. When I ran the debuger for the first time, it has upgraded the version of the P&E Multilink firmware to 5.77. But this is a problem for me. The project has worked quite well with the old 5.72. Now the program stack is exposed to unexpected nonsense writes and the application crashes. I tried to install back the CW 6.1 and recompile the project but with the same result. Is there any possibility to downgrade the firmware version of P&E Multilink? Or any other suggestion?

Thanks for your answer

Venca

I see only v5.72 on P&E site. Try going www.pemicro.com then press Support tab, then Documentation & Downloads, then firmware update. Hope downgrade is possible.

Exactly. There is only 5.72 but with CW 6.2 you get the 5.77 which is not even on the P&E support page. I thing I've got the solution for downgrade the firmware version. It is prety simple. I renamed the suffix of the firmware file from .572 to .578. Then i ran the firmware uploader from P&E support page and - hula hop - the firmware has been downgraded successfuly.

Anyway, thanks for your interest

Hi,

It is quite usual for the firmware version jammed into your USBBDM by the latest CodeWarrior (without your consent) to be a later version than is available from the P&E website. I have complained about this before, but it has never caused a problem for me, yet.

Hi,

I have to apologize to P&E Micro, their firmware may works well. The unexpected behavior of the stack was caused by my unexpected silly redefinition in the linker file . So once again sorry.

Have a nice day
