My customer has evaluated bq27520-G4 on their test board and communicate from bqStudio and EV2300. And now they are facing abnormal communication error after following procedure.
- Confirm to communicate normally at default sample
- Program default srec file that can be download from bq27520-G4 product folder by using bqStudio
- After programming, bqStudio can't see bq25720-G4 and so can't read/write any register
- This no communication error can not be fixed by removing battery
- Have you had experience such communication error?
- Do you have any method to communication with such device? I mean that can I access with maskROM mode?
Please let me communicate at off line to provide detailed customer's information if you need.
