First, thanks for the help. I have an ARM mini2440 Friendly on hardware. It is failing and we bought another to replace it. The mini2440 works with S.O. "Modified" on a SD. Linux We have tried to enable the SD in the new mini2440 through all procedures available on the Internet (u-boot, super boot, etc) We could not get boot from the SD. Is there any way to make a "backup" or DD compelto of Flash mini2440 and pass it to another? Thanks for the help.
How was the older mini2440 failing? Corrupted SD card? Have you not got backup kernel and root file system images? > The mini2440 works with S.O. "Modified" on a SD. Linux Don't understand what you mean. How did you generate your kernel and root file system? How is the SD card partitioned?
How was the older mini2440 failing? Corrupted SD card? forgive my English is not my language (google translate) It is failing mini2440 circuitry turns off sometimes. the sdcard does not fail, indeed, have two equal. Have you not got backup kernel and root file system images? no, that's my question, if I can make a "data dump" that some mezzanine card and load it into the other mini2440 but I imagine the filesystem will be in the sd not? > The mini2440 works with S.O. "Modified" on a SD. Linux Don't understand what you mean. a linux with an app How did you generate your kernel and root file system? I do not understand this, I buy the mini2440 two sdcard (it) all inclusive. the other is a mini2440 buy and I can not read the sdcard How is the SD card partitioned? I do not remember, I think it has the 3 correct partitions, but the two cards work in mini2440 not number 1 and number 2 in the mini2440 the question is, how to make the sdcard work in mini2440 mini2440 number 1 and number 2 thanks a lot
How long will the first mini2440 run before failing? Does it behave the same way with both SD cards? Do both mini2440s have the same bootloader in NOR and the same amount of flash memory? Is one mini2440 several years old?
