SPI NAND flash is programmed, but the board still fails to boot.

Hi
I used the following command line to program the board:
./tools/linux/Linux_Upgrade_Tool/upgrade_tool uf ../Luckfox_Pico_Pro_Max_Flash-20241012T074752Z-001/Luckfox_Pico_Pro_Max_Flash/update.img

and the output is:

But after flashing, the board doesn't boot.

With the log messages, we learn that uboot is not booting properly.
First, let's make sure that the download is slow or fast.
If it's fast, there may be a problem with flash.
If it's slow, it could be a firmware issue.
Did you compile your firmware yourself? Try using the firmware we provide first

[smzahraee]

The firmware upload is slow.
I tried both versions: one compiled with my firmware and the other with your firmware.

If you burned the firmware we provided, this problem should not occur under normal circumstances, please make sure that the image you burned is the corresponding hardware

[smzahraee]

Before proceeding with burning the image to the SPI NAND flash, please perform the following steps:

1. Run this command on your device to zero out the target memory:

   dd if=/dev/zero of=/dev/mtd0 bs=1k

2. After that, proceed with burning the image onto the SPI NAND flash.

Let me know if you need further adjustments!
