AM68A: Change MCSPI Drive Strength

Amandio Neves

Part Number: AM68A

Tool/software:

Hello,

We're using the AM68A with the Linux SDK v10.00.08. Is possible to change the drive strength of the spi peripherals, ideally from Linux?

Thanks!

Hi Amandio,

There is no support for changing drive strength for McSPI within Linux McSPI driver.

There are some DRV_STR fields in GPIO PADCONFIG registers, but it is recommended to keep at nominal as mentioned in this other thread for a different Jacinto7 device: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1064675/dra821u-how-is-drive-strength-set-for-the-drv_str-setting
