TMDS570LS12HDK: Is there an example how to use HDK with TPS65381EVM?

Hi Robert,

Please refer below thread, where QJ given how to use SDL as startup guide to build application on TPS65381EVM,

(6) CCS/TPS65381A-Q1: TPS65381A-Q1: TMS570LC4357 spi example code - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

Also, you can refer below application note:

Hi Jagadish,

I saw the links but there was no information on how to make hardware connections between TMDS570LS12HDK and TPS65381EVM. I need to understand what are all the connections to make to ensure testing of specific features such as watchdog, error ..
For example, just power them individually and connect SPI and the error pin, or you need to power the TMDS570LS12HDK via the TPS65381EVM as shown in the block diagram and connections between TPS65381 and Hercules MCU copied from TPS65381-Q1 Multi-Rail Power Supply for Microcontrollers in Safety-Critical Applications Data
Sheet (SLVSBC4). I believe more the latter and to do this I think it has to modify the TMDS570LS12HDK in an appropriate way.
Can you help me please?

Hi,

Apologies for the delay, i had a discussion with internal team regarding your issue and just now i got response.

Yes, you can do this. You can power both the boards differently and can connect SPI and error pin.

Hello Jagadish, thanks for the support at the moment.

I will give you some feedback after the integration tests by my internal team.

Thanks & Regards,
