Hi @oliver_chen, @jan_spurek,
I just wanted to report an error in the Programming AID for the imx8mp with ddr4 for half bus width.
Here is our working DDR4 configuration:
There is an error in the address mapping. DDRC_ADDRMAP2 must be set to 0x00000007 but it is 0x00000707. That is because D77 is fixed. The field has no formula and always remains at 7 instead of 0.
Hopefully I will save others a few hours of debugging xD
Best, Michael
Yes, exactly. That's why I reported the bug
Hi Michael,
ok, thank you for the details. I'll work on updating the RPA to correct the error.
Best Regards,
Jan
Hi Michael,
thank you for reporting this behavior. My initial analysis suggests that you are correct - could you please confirm that you have encountered calibration failures with the original configuration, which were resolved by the modification?
Thank you.
Best Regards,
Jan
