Other Parts Discussed in Thread: BQ40Z50
Hi
I made a PCB with bq20z90 and bq29930 ICs for protecting and managing my robot's batteries and the problem is that I can't change data flash values with my MCU. I know TI advises to do this job with ev2300 but this board is not accessible for me right now. I've done everything right according to slua335 but when I want to write data on SBS command (0x78) after writing subclass id on 0x77 writing fails. I can read data flashes but not writing them (voltage thresholds are OK for writing). Should I switch to Rom Boot mode?
Please help.
Thanks .
John
