IMX8ULP-EVK9 PSRAM(APS6404L-SQH-ZR) Access Issue

dhruvinrajpura — Tue, 24 Sep 2024 09:19:28 GMT

I am using the IMX8ULP EVK9, which currently has the APS6408L-OBM-BA PSRAM. Now, I would like to use the APS6404L-SQH-ZR PSRAM instead. I found example code for the APS6408L-OBM-BA in the IMX8ULP SDK. Is there any example code available for communicating with the APS6404L-SQH-ZR?

Hi @dhruvinrajpura!

Thank you for contacting NXP Support!

All our examples are available on github if you don't find the needed example doesn't exist.

Hi,

We didn't made QSPI SDR test on the IMX8ULP-EVK9, but we may find some code example from other NXP SoC & board running APMemory QSPI.

Just as an example FRDM-RW612-QSG-LR (https://www.nxp.com/docs/en/quick-reference-guide/CS_FRDM-RW612-QSG-LR.pdf) or SLN-SVUI-IOT (https://www.nxp.com/design/design-center/development-boards-and-designs/edgeready-i-mx-rt106v-based-smart-voice-user-interface-solution:SLN-SVUI-IOT?#design-resources)

hope this may help
