Hello,
We have used MPC8309 Power QUICC II Pro processor in our new design and we have the assembled prototype board ready with us.
In out initial testing we are struggling to get the UBOOT code running through NOR BOOT and we are not able to get any data on console.
Here, we are able to connect the processor core through JTAG and are able to read / write NOR flash connected on eLBC with 16-bit GPCM interface.
We are using M29W256GH70ZS6E NOR flash.
Please let us know what could be the problem here stopping the processor to get BOOT from NOR.
Also let us know if you need more information related to design.
Regards,
Pavan
Hi,
The console messages are sent after the bootloader's relocation in RAM. It could be a problem
with the DDR initialization. You sad you can read/write in flash. How did you do it, did you use the Flash Programmer
utility in CW ? I'm asking because CW downloads the flash algorithm code in RAM, so the RAM is initialized by CW
according to the target init file.
What about the flash content ? did you build a Freescale SDK that supports 8309 and wrote it into flash ?
regards
Catalin
