I have a EV2300 connected via I2C to BQ34Z100-G1 print. The communication seem ok, but I cannot change any parameter via this tool. Also the chemistry cannot changed to any of the displayed battery types from folder chemistry. There is a note in bold "Right click on the selected chemistry to apply it to individual cells. The menu appears only if the f/w supports individual cell chemistries" If I do a right click no menu appears but if I try to use the button "Update chemistry from database" a window with error 3 appears.
I have sent the file bq34z100_G1_v0_16_build_17.srec (from TI) with menu "Programming" ==> Programm and this works without a problem (512 records) but the write problem is still there.
Now I have tried to change the value status in folder "Registers" because it is the only one indicating "read/write" but this action has killed the whole data in the chip because all register have changed to dark grey and the I2C is lost and not working anymore.
Is there anybody knowing the reason why it is not possible to change/write data and/or chemisty?
Is for the BQ34Z100_G1 a special multi chemistry FW neccessary?
I have several new PCBs with this IC but is there a way to flash a corrupted BQ34Z100-G1 with new default firmware.
Thanks
