AM2434: Enable GPMC clock from GEL file

Kalman Budai

Part Number: AM2434

Dear TI,

I would like to initialize GPMC port for PSRAM access in CCS from GEL file.

I can initialize the PADCONFIG registers, can set the region and know what to write into GPMC config regiters, but can not produce clock for GPMC module becasue this function is missing:

SOC_moduleClockEnable(TISCI_DEV_GPMC0, 1);

Have you implemented it?

We have Set_MAIN_PSC_State() function defined in the GEL file which you can use to enable the LPSC gate for required clock. The function is defined in ${CCS}\ccs\ccs_base\emulation\gel\AM24x\AM24_PSC\AM24_PSC.gel file.

Hi Tushar,

thanks for hint!

It works after fixing an old bug in AM24_PSC.gel file!

The bug is here in line 201:

address_offset = 0x80000000;

It must be 0!

I have seen the same bug in CCS 12.10,12.81, 20.31.
