Subject: [U-Boot] TQM8xxL flash memory write problem
Date: Mon, 8 Dec 2008 13:03:00 -0800 [thread overview]
Message-ID: <200812081303.01727.tmaenner@aehr.com> (raw)
Hi Everybody,
for reason, I am having the following problem with u-boot 1.3.4 and 1.3.3 (no
other tested; very old versions are fine).
Using the u-boot with TQM823L_config after reloading u-boot with bdi2000,
using the following commands (see below and they worked before too)
- erase all flash; except u-boot
- download image via tftp to 200000
- copy data to flash
- fli shows both banks written to...
I noted the following:
- range 40400000 4043ffff has been written too after copying u-boot
- range 40440000 404fffff has been written too after copying kernel
Any idea on what's going on here - I'm confused... ;)
Lengthy output below.
Thanks in advance for your help
Tom
