Testing 3.3V Octo-SPI PSRAM is fine on the STM32L4P5G-DK board. I'd like to test another 1.8V Octo-SPI PSRAM now. The solder bridge options SB17/SB18 for PSRAM and SB13/SB14 for MCU are modified for the purpose. However, a certain DQ bit is still failing. What else do I have to configure accordingly?
It's strange. the bit1 of the 8 bits date is right for bit 1, bit 9 and bit 25, only fails at bit 7. can you write others liking: "fff2fdcd", "55AA55AA" or "AA55AA55"?
