Part Number: TPS65988DK

Hello,

I had a question regarding PD firmware upgrade over I2C. Which 4CC command do I need to execute, FLrr or PTCs ?

Thanks!

Hi,

The FLxx commands are used to download the patch to an external EEPROM via the EC.

However, the PTCx commands are used to program the patch to the SRAM of the PD controller directly via the Host.,

Therefore, this depends on which type of operation you would like to perform.

Thank you,

Hari
