i can boot and decrypt RBF if i program the ekp file (voltile key ), but i need it to decrypt using the fuse which i already programed to the board.
thanks for your help.
When you mention boot, is it related to Arria 10 SOC ARM booting?
May I know how do you program the ekp file for non-volatile key?
and also, can you describe how you program. boot and decrypt the ekp forvolatile (the success one)?
yes i am using HPS , after i generated the ekp file i convert it to .jam file and programed it using this command "quartus_jli -c 1 key.jam -aKEY_program"
but the system after i boot it up keep resting unitle i program the voltile key using "quartus_jli -c 1 key.jam -aKEY_CONFIGURE " then it will decrypt the RBF and will boot the Linux kernel .
May I know which USB blaster you are using?
There two things you can try here:
1.Can you try to performed “quartus_jli -c 1 key.jam -aKEY_VERIFY”.
This to unsure the FPGA key is programmed correctly. Refer to table 16 in AN556,
2.May I know how do you generate the rbf file? I suspect that the rbf file generation is setting it to volatile key.
For 20nm FPGA (Arria 10), both volatile and non-volatile key can exist in a device. User can choose which key to use by setting the option bits in encrypted configuration file through the Convert Programming File tool or the Qcrypt tool.
I suspect your issue, it is always trying to read the key from volatile. you need to change the option bit that it is reading the key from non-volatile key. Refer to table 4 in AN556,
I hope this will help.
