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.
Sergey,
We are looking the procedure to blow the eFUSE values to boot from SATA interface for IMX6 based device. did you find the procedure to blow the eFUSE using UART or USB interface or is there any tool to do the same.?
