AM6548: AM6 HS EVM with Prebuild image 6.03.106 is not working...

Rio Chan

Part Number: AM6548

Hi Champs:

I download the AM6 HS 6.03.106 prebuild image, and flash the SD card, the EVM console gives me this log, how to solve it?

THanks.

This looks similar to https://e2e.ti.com/support/processors/f/791/t/889753?TMDX654IDKEVM-DDR4-memory-issue but that seems like it was just a HW problem with a single board. Do you have another different board that you can try with this same boot image?

Regarding the Micron memory part difference, this is what the board design owner stated: "The DDR part did change for the later revisions of the board but the new part was tested with the initialization and found to be compatible."

So there is not expected to be any software changes associated with the newer memory parts on the EVM.

I'm trying to find out if there is any standalone memory test program to try (for example, something the board manufacturer could have used to check the board before shipping), but in the meantime the best debug approach I can suggest is to try another board.

One final suggestion here is to try and load and run the board memory diagnostics that are part of the Processor RTOS SDK:

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#diagnostics

For this case, the mem_TEST and memStress_TEST would be appropriate.
