IMX6SLL boot config

vlintilhac — Mon, 01 Mar 2021 21:40:58 GMT

Hi,

I'm on a custom board with a IMX6SLL chip.

I'm debugging using a JTAG link and would like to change the boot configuration through the JTAG port.

I want to use the SD card as the boot device, but I don't have access to the LCD_GPIOs used to override the BOOT_CFG signals.

Can I use the JTAG to change the booting configuration and set the SD card as the boot device? What registers should I modified to achieve it? And what address should I point to reboot the chip using the new config?

Best,

Vincent

Hi Vincent

in general boot configuration is latched at POR in SRC_SBMR1, SRC_SBMR2 registers

(read only),described in sect.41.7.2 SRC Boot Mode Register 1 (SRC_SBMR1)

i.MX 6SLL Applications Processor Reference Manual

so seems it is not possible to use jtag for changing the booting configuration.
