Other Parts Discussed in Thread: EV2400, BQSTUDIO
Tool/software:
Hi,
I designed the circuit using BQ40Z50-R1 board and I used EV2400 as a debugger. So When i connected the board with EV2400, I woke up the board by jumping VPACK+ to VBAT and EV2400 could find the device so when i moved the jumper out it couldn't find the device at all.
At first, I tried to use the EV2400 to control DCHG FET by toggling from off to on in BQstudio and then EV2400 found the device. After that, I toggled again from off to on, It couldn't find the device.
When I used EVM Board, the EV2400 easily found after wake-up without disconnecting device or requiering to toggle DCHG FET in BQStudio.
I attached my schematic for additional information. I am not sure i do anything wrong or not please kindly check.
