i.MX7 SDQS polarity inversion

Hello community,

Using boundary scan tools we realized that our custom hardware has a fault:
for DRAM SDQS1 and SDQS3 the positive and negative signals are swapped.

Traces are 100µ and burried so there is no way of accessing these.

Is there any way to swap the polarity of these in hardware?

Regards,

Lars

Hi Lars

I am afraid there is no software settings for changing SDQS polarity.

Best regards
