Subject: [U-Boot-Users] flash memory access
Date: Sat, 1 Mar 2003 11:42:47 -0800 [thread overview]
Message-ID: <20030301114247.A9169@europa.queda.net> (raw)
Hi, I am having difficulties figuring out what is going on with my board
setup.
I am able to read flash memory, set the write-protect on it okay, but when I
try to erase, or write flash memory, the system hangs.
I run the command:
> Saving Environment to Flash...
> int> Protect off 25080000 ... 2509FFFF
> Un-Protected 1 sectors
> Erasing Flash...Erasing sector 135/135 ... a
(with some of my debug code in there)
Flash memory starts for me at: 0x24000000
I have an Atmel chip, 32Megbyts, 256 * 128K sectors.
Reading through the manuals for the board, and the flash chip, I am unable to
find any relevant docs when it comes to erasing / writing issues.
Anyone have any comments which might help me out in this situation?
Thanks!
- Paul
