TPS65987D: TPS65987D custom board without external FLASH - error flag after patching

Marko Kastelic

Part Number: TPS65987D

Hi Conner,

I would like to continue from where we stop: e2e.ti.com/.../tps65987d-tps65987d-custom-board-without-external-flash

We receve new HW, whit configuration as you propose (BP_WaitFor3V3_Internal).

Now mode is in APP state, and the error flag after the patching is still present.

Any further options to investigate?

Best Regards,
Mare

My apologies for the delay Mare.

I will review the full documentation for patch mode, try to emulate your problem and provide feedback by this Wednesday, EOB.

Kind regards,

Could you provide me with your BUSPOWERZ configuration, as shown in the attached image?

Additionally, are you able to provide the I2C traffic logs for your attempt to load the patch bundle from the external controller? This will allow me to further troubleshoot your issue.

Kind regards,

Conner Gillette
