Can you make short instruction how to get correct adress
Can you make short instruction how to get correct adress for s905x ?

Unify the two repos amlogic-usbdl tool
Hi @Raxone ,
I've checked both repos ( this and for s905x3) and the diff shows just this single difference.
Could I send a MR with cmd args to select the correct SoC so that the tool could be unified?

A way to decrypt AMLSECU! boot image?
Hello. In your last commits I've found some commented out lines about boot.img decryption. And i want ask you about offset and length in this dd command:
#dd >/dev/null if=boot.bin bs=1 skip=2304 count=9734268 of=boot_enc.bin status=none
How are they calculated? Do you know a way to decrypt an amlogic encrypted boot.img?
Sorry that I opened an issue, don't want to contact via email
