I have some questions regarding this document:
Section: 3.3.2. Generate SB file for FlexSPI NOR image encryption and programming
The bd file sets BEE_KEY0_SEL to b10 and BEE_KEY1_SEL to b11.
#6. Program BEE_KEY0_SEL and BEE_KEY1_SEL
load fuse 0x0000e000 > 0x06;
- Why is BEE_KEY1_SEL being set at all, when only the PRDB0 block is being used?
- Why is BEE_KEY1_SEL being set to b11 which is the SW_GP2 key? SW_GP2 has not been set in this example.
- BEE_KEY0_SEL is being set to b10 which is the OTPMK key. Where is the OTPMK key being set?
- When I tried setting BEE_KEY0_SEL and BEE_KEY1_SEL b10, the device would not boot. But when I used BEE_KEY0_SEL=b10 and BEE_KEY1_SEL=b11 like the example, it does boot. Why is this?
I am using the RT1020-EVK.
Thanks and regards,
