CCS: According to the BQ28Z610-R1-TR file to modify the initial password of the fuel gauge, why can’t it be modified successfully? Is there something wrong with my configuration?

Hello,

It looks like you are not performing the second command for the checksum.

"Starting address 0x60, data block (hex) is [0A 0C] (checksum followed by length)

Checksum = 0x0A = ~(0x35 + 0x00 + 0x23 + 0x01 + 0x67 + 0x45 + 0xAB + 0x89 + 0xEF + 0xCD). The final checksum is the bitwise inversion of the result"

Hello,

I have tried the operation in TRM, but it was not successful. Can you provide a screenshot or instruction of successfully changing the initial password

Here is a screen shot of successfully changing the initial password. Also make sure the second key is sent within 4s of sending the first one.

Thank you very much for your help. After many attempts, I finally succeeded. The key to success is to send these commands in a short time. The success of one-time modification is very low, you need to use the microcontroller or host computer to send commands, the success rate should be higher
