TMS320F28377S: Access to the peripherals from the CLA

Jean-Philippe Verschueren

Hello,

I am running code in task #1 of the CLA on a TMS320F28377S.

I can read values from ADC and write values to the DAC within the CLA task, but GPIO writes and writes to PWM registers do not work.

Any idea?

This is solved for the GPIO by adding:
GpioCtrlRegs.GPACSEL3.bit.GPIO16 = 1
This selects CPU1.CLA1 as owner of the Pin
