Hi Rogan,
OK, so the width is definitely 8 bit and not 16 bit:
static struct physmap_flash_data dns323_nor_flash_data = { .width = 1, ...
But the base address is listed here as 0xf4000000:
#define DNS323_NOR_BOOT_BASE 0xf4000000
Hmmm, maybe I must try changing that, then. That might be the answer to all the confusion.
Although it is definitely an 8MB flash, and I thought it was supposed to be at the end of memory?
Are you sure you got this right? Nevertheless, now we know for sure, that the NOR chip is connected as an 8bit device and the chip is operated in byte mode. So all tests from the U-Boot prompt should be done with ".b" extension.
BTW: This code you referenced is also available in mainline kernel.org.
Yes, I eventually got my "git clone" finished.
Thanks again for your help!
