Hi,

There is EEPROM Recovery Enable in 8.5.5.1 Serial ROM eFUSE Configuration of i.MX 6Dual/6Quad Applications Processor Reference Manual.

Is this flag a function to perform what concretely?

Best Regards,

soichi

Hello,

From section 8.9 (Recovery Devices) of the RM :

"The Chip supports recovery devices. If primary boot device fails, boot ROM will try to

boot from recovery device using one of I2C or ECSPI ports.

For enabling recovery device BOOT_CFG4[6] fuse must be set. Additionally Serial

EEPROM fuses must be set as described in Serial ROM through SPI and I2C."


Have a great day,
Yuri
