bqStudio unseal cmd for bq78350

Other Parts Discussed in Thread: BQ78350, BQSTUDIO

Hi Tom:

I am using the bqStudio to test bq78350. I changed the security key in Advanced Comm SMB, as:

Write Block 44. word 0* 35 00 23 01 67 45 FF FF FF FF

I assumption is my unseal key should be 01234567, and Full Access key is FFFFFFFF. But when I tried to unseal the chip, when I push the "UNSEAL" button on Commands and input 01234567 as my key, the Log Panel only shows me 0*1234567, without the first 0. So is there any other way to unseal the device?

I also tried input 0123 and 4567 in the "Manufacturer Access" in the Registers, but it didn't work either.

Thanks!

Chen
