Hi. I have problem.
I have custom board with iMX537 processor. In project I haven't placed switch to configurate processor via GPIO (set eFUSE via GPIO).
I reference manual I've found serial protocol description to configurate processor via uart. Also, there says what via uart user can programm eFUSE. But I can't do that. For example, I send next command via uart
02 02 00 00 08 14 08 00 00 00 00 00 00 00 19 00
This command is for configurate CFG3[7:0] eFUSE
I receive ack
56 78 78 56
After that I send next command
01 01 00 00 08 14 08 00 00 00 01 00 00 00 00 00
And receive ack
56 78 78 56 02
But I wrote 0x19 and I've read 0x02.
In reference manual says, what 0x00 00 08 14 is the addrress for CFG3[7:0] eFUSE.
Can anybody help me to undestand how can I programm eFuse via uart.
