TPS65991EVM: encountering problems using TPS65991BH.

Hi,

Currently our board is encountering problems using TPS65991BH.

Currently, according to the recommended settings of Intel BKC (Best Know Configuration),

we will encounter the problem that the TYPE-C side cannot run USB 3.2 (only runs USB2.0) and the DisplayPort Alternate Mode cannot be displayed.

We have borrowed a CRB from INTEL, and the CRB uses TPS65991AE. TPS69551AE and TPS65991BH use different Firmware versions.

If CRB is set according to Intel BKC, it will encounter the problem that the TYPE-C side cannot run USB 3.2 (only USB2.0) and DisplayPort Alternate Mode cannot be displayed.

The original burning firmware test of the TPS65991AE EEPROM on INTEL CRB is normal, but when reading its EEPROM, it can only read the BIN file, and its TI GUI Tool settings cannot be known because the AE and BH Firmware versions are different.
Is there any recommended method to apply to TPS65991BH?

Thanks & best regards,
