I have a TPS65988D, and it seems stuck in PTCH mode. I have a system without SPI flash and want to get the board into APP mode so I can interface with the registers and full 4CC commands (I need to turn on power role swap depending on state of the rest of my board). Most registers just read all 0s in this mode. I tried to simply send a PTCc to get the board to skip patching and boot a default configuration.
I first issue an unlock and then a PTCc. However, this doesn't work - board no longer reads PTCH, just reads all 0s for mode, and likewise most every 4CC command returns 0s but has no discernible effect. Could someone please send me the file "TPS65987DDH Host Programming for SPI-Flash Less Systems" Application Report: SLVA972? I believe this is likely to answer my questions.
Thank you!
