Other Parts Discussed in Thread: BQKEYPACKAGER, BQKEYPROGRAMMER
hi Team,
pack houses want to check the method on modify the SHA-1 key on the bq40z50-R4 IC
from the TRM we saw the method of changing the Authentication Key has the option of
SHA1_SECURE = 1 or 0
they are asking that once they changed the key, do they just need to export the SREC image and program it on to other ICs?
or each IC will need to have the key changed via the command sequence?
is the following understanding correct?
SHA1_SECURE = 0
Should able to program the SREC image to other IC to maintain the modified SHA-1 key
SHA1_SECURE = 1
Should need to send the command to change SHA-1 key in secure memory for every IC.
