Thanks Keerthy!

We are using GPMC bus to talk to FPGA memory.in synchronous mode

Currently k3-j721e-main.dtsi file doesn't have definition for GPMC. Could you please share the procedure to enable GPMC in uboot?

Please let me know if you need further information

Hi Swapna,

There is NO support for GPMC in U-Boot from the DRA829 SDK. There is no plan to enable in the next SDK as well.

Hi Keerthy,

Can TI provide guidance on how we can configure GPMC in uboot?

Is GPMC supported in Linux (TI SDK 8.6.01)?

Thanks,

Swapna

Hi Swapna,

There is no reference for Gpmc. It's not supported in Linux either on DRA829.

Best Regards,

Keerthy
