We have Cell Temperature Model Coeff A1 at 0x454F becoming corrupted on a B78350-R1.
As a matter of fact, our software writes the Electronics Load register at 0x454E.
Although the range is 0-255, the documentation specifies a 2 bytes register. We therefore write 2 bytes. See TRM section 9.1.13
bqStudio (1.3.45) displays the correct value in the Electronics Load register but that value also lands right in the A1 coefficient MSB!
It looks like a registers conflict.
What do you think?
That was not happening in pre-R1 firmware.
According to bqStudio addresses, many registers have moved between releases (see snapshots attached). Cell coeff a1 is one of them.
This changes does not appear in the release notes and the latest R1 Technical Reference Manual matches pre-R1 release (see p.151).
What's the truth?
