Hi!

Have custom pcb based on IMX6ULL.

Currently it boots using GPIO setup:

BOOT_MODE0 = 0, BOOT_MODE1 = 1,

 

BOOT_CFG1[3:0] = 0

BOOT_CFG1[7:4] = 0011 - Serial SPI

 

BOOT_CFG1[7:0] = 0

 

BOOT_CFG4[2:0] = 010 - ECSPI3

BOOT_CFG4[3] = 1 - SPI addressing 3 bytes. 

BOOT_CFG4[5:4] = 00 - CS - SS0 selected

BOOT_CFG4[6] = 0 - Disabled EEPROM recovery

 

We need to set booting interface using J-link for mass production. Able to connect to pcb using JTAG and detect MCU. Not sure how to burn fuse modes according to configuration above. Does anyone has experience with it?
