These are not official test images for the RK33xx and rk3288 rk3188 platform.
Pay attention. Starting from version (20200826), the configuration order for the used DTB changes.
Please note that the algorithm for initial configuration of the system for startup has changed. Instead of a file "uEnv.txt", the file "/extlinux/extlinux.conf " is now used. The rules for editing a file remain the same.
After writing the image, you must correctly configure the DTB used in the file uEnv.txt
Images rk3328 and r3399 and 3288 are universal, when starting from USB media images are interchangeable (the only difference is used for the image u-boot and UART console output settings). Tar archives for updating are also universal.
Note that the new generic images now use a single download directory.
Important. Changed the directory location of the images. Now all images (for all supported platforms) are in one place.

Add u-boot to SD card
If you have any working system on the SD card that starts normally, you will be able to check the LE. You need to try to replace the u-boot in LE, on the version with a working SD card. You need to perform a few additional steps when preparing an SD card.
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=442
dd if=u-boot-rockpro.img of=/dev/<new_SD_card_LE> conv=fsync bs=512 skip=1 seek=1
After that, you can try running LE on RockPro. The last two commands write a working u-boot and save the existing partition table for the system written to the SD card. By the way, in the same way you can replace u-boot for Armbian system and check the start of any image.
