Hi Igor, as I told you, I,m trying to configure the fuse resistors and while y was studiying the ultralite EVK board schematics i ´ve found some extrange thing, the board uses the USDHC1 bus but the fuses are set to USDHC2, see the picture below
I´ve also noted that the real development board is configured to perform internal boot
Can i ommit thhis programing resistors :
"Setting BT_FUSE_SEL=0 forces the ROM code to jump directly to the Serial
Downloader. This allows a bootloader to be downloaded which can then provision the
boot device with a Program Image and blow the BT_FUSE_SEL and the other boot
configuration eFUSEs. After reset, the Boot ROM code determines that BT_FUSE_SEL
is blown (BT_FUSE_SEL = 1) and the ROM code performs internal boot according to
the new eFUSE settings. This allows a user to set BOOT_MODE[1:0]=00b on a
production device and burn fuses on the same device (by forcing entry to the Serial
Downloader), without changing the value of BOOT_MODE[1:0] or pullups/pulldowns
on the BOOT_MODE pins.

Do you recommend me to place the programming resistors anyway?
My roadmap is as folows:
Patch a kernel for PF3001
download the image to the emmc with serial downloader and programming efuses at the same time
then perform reset and the board should boot fine
