My suggestion is use timeout of some command when is possible

I think that is kind of good example

Thanks for sharing the example.
I adapted the UUU script like this:
SDPS: boot -f flash.bin
FB: ucmd setenv fastboot_buffer ${loadaddr}
FB: ucmd mmc dev 2 1
FB: download -f flash.bin
FB: ucmd setexpr blkcnt $filesize + 0x1ff
FB: ucmd setexpr blkcnt $blkcnt / 0x200
FB: ucmd mmc write $loadaddr 0 $blkcnt
FB: reboot
FB: done

Create an lst file
Hi Fabio
Top posting
# @_flash.bin| bootloader
# @_image [_flash.bin] | image burn to nand, default is the same as bootloader
# @_filesystem | filesystem to burn
# @_kernel | kernel image
# @_dtb | dtb image
# This command will be run when ROM support stream mode
# i.MX8QXP, i.MX8QM
SDPS: boot -f _flash.bin
FB: ucmd setenv fastboot_buffer ${loadaddr}
FB: download -f _image
# Burn image to nandfit partition if needed
FB: ucmd if env exists nandfit_part; then nand erase.part nandfit;
nand write ${fastboot_buffer} nandfit ${filesize}; else true; fi;
FB: ucmd nandbcb init ${fastboot_buffer} nandboot ${filesize}
FB[-t 1]: ucmd ubi part nandrootfs
FB[-t 1]: ucmd ubi create root -
FB: download -f _filesystem
FB[-t 6]: ucmd ubi write ${loadaddr} root ${filesize}
FB: download -f _kernel
FB[-t 1]: ucmd nand write ${loadaddr} nandkernel ${filesize}
FB: download -f _dtb
FB[-t 8000]: ucmd nand write ${loadaddr} nanddtb ${filesize}
FB: reboot
FB: done
You can just change as you want. We have this file in buildroot, uuu
can run command on the device
using FB command. Example how call it
${OUTPUT_DIR}/host/bin/uuu -v -b ${IMAGES_DIR}/nand-full.lst \
${IMAGES_DIR}/flash.bin \
${IMAGES_DIR}/flash.bin \
${IMAGES_DIR}/rootfs.ubifs \
${IMAGES_DIR}/Image \
${IMAGES_DIR}/freescale/imx8mn-bsh-smm-s2.dtb

imx8mp: Flashing U-Boot into eMMC hardware partition via UUU
Hi, I am using an imx8mp-evk board and I can flash the U-Boot into the eMMC hardware partition 0 by running: => tftpboot $loadaddr flash.bin => setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200 => mmc dev 2 1 => mmc write $loadaddr 0 $blkcnt Now I want to do the same via UUU. I tried to create a script called emmc_flash: uuu_version 1.5.21 SDPS: boot -f flash.bin SDPS: done FB: ucmd setenv fastboot_dev mmc FB: ucmd mmc dev 2 1 FB: flash bootloader flash.bin FB: Done Then on the PC: uuu emmc_flash U-Boot is loaded to RAM, but the eMMC hardware partition is not programmed. What is the correct script for doing this? Any suggestions? Thanks
