Other Parts Discussed in Thread: EV2400, BQSTUDIO
Tool/software:
Hi,
I am having significant issues program the BQ7694204PFBR chip, this is the SPI variant with CRC inbuilt, on my custom PCB. I recently bought the EV2400 as I had the feeling it was my lack of programing skills but my issues remain. May you have a look?
3v3 out from Reg1 is working.
With the logic annalyser using my own code, the best result I recieved from MISO was 0x00.
Using eval board EV2400
EV2400 was updated as of 24/05/2025. When using the BQstudio It is not automaticaly registering the chip and if I manual select the BQ chip, still no success, error message recieved is " No aknoledgment from device". This testing was with both "pack -" and "GND" as I wondered if the issue stemmed from the two ground positions.
Connections were made through port 5 on the eval kit according to this other thread
Thanks in advance,
Tomás
