TPS25750: issue load patch bundle burst data from MCU

Part Number: TPS25750

Tool/software:

I am trying to use TPS25750 without EEPROM.

I followed procedure in https://www.ti.com/lit/ug/slvuc05a/slvuc05a.pdf?ts=1736841456155 to use MCU to load configuration file to TPS25750 through I2C.

However, at the end, after PBMc command, when I read the output date from PBMc command, the byte 26 (bit 207:200) is 0x03 (AC_LOADING_FLASH).

TPS25750 doesn't work as expected although it is in APP mode. This makes me wonder if there is something wrong during the configuration download process.

Please help.

Thanks.
