Other Parts Discussed in Thread: BQEVSW, EV2400
Hi,
I was trying to flash DFI on our board while the board was powered by battery pack. But during the flashing process, I got communication error. After that the bqEVSW only shows No acknowledgement: VB_T2H_NACK. Now it cannot auto-detect the device. SBS window is blank. Reading SBS command 0D on Pro screen shows same error. But I can still measure 3.3V on REG33 and 2.5V on REG25. Is there anything I can try more or shall I assume the device is dead?
It happens every time when I try to flash without power adapter connected on the PACK± side. EV2400 and bqEVSW are fine because they work with another board.
