Hello all,
We are having difficulties with the SDRAM of our second generation of custom rt1064 board. Additionally, we are using the same SDRAM as the EVK.
There is no difference in design, position & rouring of the MCU & SDRAM module compared to the first generation.
However, first we noticed that the MCU would not boot on Zephyr RTOS and then testing it on MCUXpresso with SEMC sample we noticed that the first write/read always fails and the write/read only works properly after the second write/read.
Any help would be appreciated!
SEMC SDRAM Example Start!
