[U-Boot] OMAP3: NAND init problems
by Simon Schwarz 20 Jun '11

20 Jun '11

Hi list, I'am trying to get the NAND-flash to work in my OMAP3 SPL. I essentially call these functions after the base init: gpmc_init(); nand_init(); But in nand_init() the cpu jumps somewhere in memory. I tracked that down to nand_get_flash_type() to the call chip->select_chip(mtd, 0); Some digging shows that the select_chip function pointer isn't initialized -> just garbage. Just before the call to nand_get_flash_type() is a call to nand_set_defaults(chip, busw) which IMHO should be responsible to set the function-pointers. But this function tests for non-zero value -> garbage is non-zero. Do I miss something for NAND init? Thanks in advance! Simon

Hello, I can't find this patch applied in the U-boot sources (or any of the forks). Is this functionality going to be merged into U-Boot ? Did I miss something ? Any answer would be greatly appreciated. Thanks, B.R. Vilo

[U-Boot] at91rm9200 linking problem (?)
by Marcin Górski 20 Jun '11

20 Jun '11

Hello, I'm trying to port U-Boot to ARM&EVA board (with AT92RM9200 cpu). I'm a little bit confused about usage of CONFIG_SYS_TEXT_BASE macro. As mentioned many times before U-Boot shouldn't be run from RAM, so I set CONFIG_SYS_TEXT_BASE to point a DataFlash memory. But when I do that not only .text section but also .data and .bss sections are linked to flash memory. When I run U-Boot I get "prefetch_abort" exception (which I believe is due to invalid memory location access). On the other hand, when I set CONFIG_SYS_TEXT_BASE to point to RAM location U-Boot hangs just after the start: U-Boot> go 0x22000000 ## Starting application at 0x22000000 ... U-Boot 2011.03 (Jun 20 2011 - 00:56:19) DRAM: 1 MiB To load a new image I use an old version of U-Boot (1.1.6) that was previously installed on this board. This is the very first time when I use U-Boot , any suggestion will be appreciated. Best regards, Marcin
