Today I tried to reflash a
SIE platform which is one top side with two layers pcb, so all the parts on top sides. I replaced a 64MB instead of 32MB. After that, I can not reflash rootfs image at some blocks and got fail.
My test script file is as:
#!/bin/bash
ROOTFS=openwrt-xburst-qi_lb60-root.ubi
sudo usbboot -f ./usbboot_2gb_nand.cfg -c "boot"
sudo usbboot -f ./usbboot_2gb_nand.cfg -c "nerase 16 512 0 0"
sudo usbboot -f ./usbboot_2gb_nand.cfg -c "nprog 2048 $ROOTFS 0 0 -n"

Device unboot! Boot it first!
The root cause was that I didn't clean soldering paste well with cleaner around SDRAM. Actually this is surprised for me! Since I frequently didn't clean soldering paste after rework or repair while faced over than or equally 4 layers pcba. So this implies another phenomenon. The data bus run along only top side is really dangerous and easily encountered unexpected equivalent impedance caused by other materials mixed with buses.
