1. Remove from working SD card u-boot. This can be done with this command on a Linux PC.
dd if=/dev/<name_you_SD_works_card> of=u-boot-rockpro.img bs=1M count=16
2. Write LE to SD card, configure DTB and replace u-boot with taken from working SD card. U-boot replacement is performed by two commands.
dd if=u-boot-rockpro.img of=/dev/<new_SD_card_LE> conv=fsync bs=1 count=442dd if=u-boot-rockpro.img of=/dev/<new_SD_card_LE> conv=fsync bs=512 skip=1 seek=1
balbes150 , on my A5X Max+ i can't boot from SD and i need to write to eMMC your images with rkdeveloptool wl 0x0 imageName.img directly to test it, it is indicated on that thread:
LibreELEC on RK3328 A5X Max plus
About your information to replace u-boot on first post of this thread, does it work making these dd commands on image files instead of partitions like following example?:
# To save
dd if=imageThatWorksForMeToWriteToEmmc.img of=u-boot-ubootoktobootfromemmc.img bs=1M count=16
# To inject on an image to test
dd if=u-boot-ubootoktobootfromemmc.img of=newImageToTest.img conv=fsync bs=1 count=442
dd if=u-boot-ubootoktobootfromemmc.img of=newImageToTest.img conv=fsync bs=512 skip=1 seek=1
Or do i have to use another type of commands to prepare image before writing to eMMC?
I have detected too on image that i tested first:
LibreELEC-ARMv8.arm-9.80-devel-20200923123657-569f834-rk3328-old.img.gz
That mac addres of eth0 is changed on every reboot and it does not work adding on extlinux.conf APPEND this string at the end to fix it:
mac=<MacAddress>
And if i configure manual ip address on my ethernet connection when i reboot it is changed to dhcp and receive different ip addres for my new mac. I need to assing a fixed mac address or a fixed ipaddress, how i could do it?
Thank you very much for your time!!
