[讨论]我也杯具了。NAND读写功能被关闭，自制彻底与我无缘了。

學到一招,仔細讀讀NAND的規格書吧

Bad flash to nand ? recovery!


If like me you are rushing around, and accidentally flash a xenon xell image to a zephyr or other board, then there are two things you'll notice
1) it won't power up dead as door nail.
2) the nandpro program won't recognise the flash chip any more so you can't write the correct image to the chip. OH DEAR!!!
There is help though by shorting a couple of pins on the nand.


This is what you nand looks like, you'll notice in the top left hand corner a dimple on the chip that is signifying pin 1.
This is a shortened chip with leg/pin numbers.
the objective is to prevent the SMC from retrieving its instruction code/firmware, by shorting and confusing the data lines.
I shorted pins 44-47 with a flat head screw driver (gash I know).
sequence of events,
I disconnected power brick,
shorted pins,
connected power brick,
un-shorted pins (removed screwdriver)
ran NandPro 2.0b. It now shows correct flashconfig again hooray!!
Pins 44-47 are I/O pins don't carry any voltage so to speak so chances or blowing something is less but not impossible so only do this if you are completely stuck and the alternative is to remove the chip bench program it.
Re-flashed with correct xell image booted linux flashed xbr all is fine now phew!!

LS英雄，这段的意思是说短接44和47呢，还是44至47一起短接呢？另外，是断电情况下短接呢还是插电不开机的情况下短接？还是断电的情况下短接，然后开机，然后用NANDPRO读取呢？

回楼上，这个我没试过，我英文也不是很好，不过我理解是44-47都短接，别的我也说不清了

哎，餅都擺在你嘴邊了，就看你咬不咬了。如果英文實在看不懂的，可以試一試google的翻譯機，也應該89不離10。
