Dear all

 

We succesfully designed a custom board based on the I.MX6UL Processor,
DDR3 Calibration and stress tests run very good but when running mfgtool uboot stops

 

We have PF3001 A7 PMIC

 

It seems to be a hardware missmatch expecting PMIC PFUZE100

Also we have 512MBDDR3 instead of 1GB

 

We need to make uboot advance in order to blow efuses

 

 

I´ve added this to UCL2 to boot from SD1 overriding GPIOS (WE HAVE NO CONFIG RESISTORS) but it seems to not being working

 



I WANT TO ADVANCE TO UBOOT to perform :

FUSE PROG 0 5 0X00000040
FUSE PROG 0 6 0X00000010


Because the mfg burn comand is not working

Thank you so much
