Original question:
Part Number: AM4376
Tool/software: Linux
Hi All,
We are also trying to interface 128(MX66l1g45) MB flash.
We successfully boot from QSPI NOR flash when we limit our access upto 64MB(We made flash partition upto 64MB in device tree).
When we increased the size of partition above 64MB we get error.
Please guide me on following:
Is it limitation of AM4376?
Or is there any alternate way to access upper 64MB?
Regards,
Dhananjay Patil
Hi Marcus
Please find attached device tree and error message
Regards,
Dhananjay Patil
