CCS/TMDSIDK437X: IDK initialization at 1GHz

Hi,

i would like to run an TI RTOS application for the AM4379 at 1 GHz. Are there any .gel files or a bootloader with 1 Ghz support for the AM437x IDK board?

Best regards,

Michael

Michael,

this can`t be done purely using the gel file to setup the clocks. Setting up OPP_TURBO (as described in the datasheet) requires change of core voltage and then ramping up the MPU_DPLL clock. Ramping up of the DPLL can be done using GEL files but to do the core voltage chnage on the IDK, you need to use the PM and the I2C drivers.

Hope this helps.

Regards,
Rahul

PS: To help with the clock setup, you can refer to the AM437x DPLL spreadsheet that I have attached here:
