[U-Boot-Users] 1.1.6 at91 based board dataflash copy panic.

[Ivan Kuten <ivan.kuten@promwad.com>]

Hello,

I had the same problem with u-boot with dataflash only setup
 (no NOR flash) and used the following patch (see attach)

cmd_mem.c doing wrong when copy from Dataflash to SDRAM:

-       if (addr_dataflash(addr) && !addr_dataflash(dest) &&
(addr2info(dest)==NULL) ){
+       if (addr_dataflash(addr) && !addr_dataflash(dest)
+#ifndef CFG_NO_FLASH
+           && (addr2info(dest)==NULL)
+#endif
+          ){

and do not forget to set CFG_NO_FLASH in your include.

 Hello all,

We are trying u-boot 1.1.6 on a customised at91rm9200 board. The main
features are dataflash, 32MB and networking with DM9161.

We have been using u-boot 1.1.4 quite well now, but we would like to test
1.1.6. Kernel boots ok, but we have found a problem.

When we do a cp from the dataflash to ram like this:
cp.b $(kerneladdr) 0x21600000 0x1
where kerneladdr is 0xC0040000

we have the following:

data abort
