I have a TPS25750D EVM and also I made a TPS25750D demo board .
1.in my demo board , the chip's LDO_3v3,LDO1v5 is short to GND ,I do not know why ,previous time with the FW ,the PD can be a source well can charge the laptop and phone with 9/15/20v.
2. then I change a good chip from the TPS25750EVM to the demo board ,after I installing the good one in my demo board ,the chip always in PTCH Mode , then seems my FW in the external EEPROM does not load ,so I cannot use my demo to charge the device like phone and laptop ,the FW is good in previous board .
can you tell me how to change the PTCH mode to APP mode ?
I use aadvark to send the IIC cmd and flash the EEPROM
Another issue is that how can i issue the 4CC cmd by aadvark ?
