internal boot from uSHC2

[lk22]

Hi,

We are using i.MX6 Solo processor. For that we are using boot mode 10 (internal boot mode) and done GPIO setting for boot from uSHC--2 (microSD card). But it is not booting from it. I have checked the clock and command lines, but I have not seen any activity there.

In boot mode 00,  because of manufacturing mode it is booting from uSHC--2 (microSD card).

I have checked all the GPIO settings. For reference I have attaché d the GPIO settings.

With regards

please try to set all unused (don't care) BOOT_CFG3

and BOOT_CFG4 pins to GND.

Also could you read register SBMR1 & SBMR2 ?

Thanks Igorpadykov,

The problem was with BOOT_CFG4[7] only. It was not working with the existing resistor values. On reading SBMR1 & SBMR2, I was able to know that.

also I would suggest to try check log buffer (usage described on link below),

with jtag check ROM address 0x000000d8, it contains pointer (0x00901AB8) to internal RAM

location where boot log buffer is stored. Can you send first 256 bytes of that buffer

for check.
