We want to write our own burning and testing utilities. At this time we want to use the OSBDM to access the BDM and be able to read/write data from a PC and run some diagnostics as well.
We were able to find only one document https://www.nxp.com/docs/en/user-guide/OSBDMTAPUG.pdf
We need the latest and relevant documentation for OSBDM/USBDM especially in the context of S12Z.
We also want the latest software for OSBDM both as firmware and more importantly for PC DLL/libs so that we can write the application we want.
We have of course gone to PEMicro OSBDM page but it almost feels like they don't want anyone to use OSBDM. Even the libraries of OSBDM from PEMicro are not free ($199+)
Is NXP/Freescale not interested in OSBDM being used? Why is there such poor support !
You can refer to:
Open Source BDM interface: OSBDM
USBDM: Debugger interface for Freescale RS08,HCS08,HCS12,Coldfire and ARM-Kinetis Devices.
Or you can try to look at and TBDML community.
However, I recommend you to contact PEmicro support https://www.pemicro.com/support/index.cfm
I hope it helps you.
