* [U-Boot] [PATCH] scb9328: Add ARM relocation support @ 2011-06-09 11:36 Torsten Koschorrek 2011-06-09 14:34 ` Stefano Babic 0 siblings, 1 reply; 6+ messages in thread From: Torsten Koschorrek @ 2011-06-09 11:36 UTC (permalink / raw) To: u-boot This patch fixed compiler errors due to missing definitions of CONFIG_SYS_SDRAM_BASE and CONFIG_SYS_INIT_SP_ADDR. The board doesn't start, though. A v2 of this patch or a seperate patch will fix the error when it was found.

If you have more as one bank, the size is the sum of all banks. In dram_init_banksize() you setup more as one bank if CONFIG_NR_DRAM_BANKS > 1. Then you should set in dram_init: size1 = get_ram_size((volatile void *)SCB9328_SDRAM_1, SCB9328_SDRAM_1_SIZE); #if ( CONFIG_NR_DRAM_BANKS > 1 ) size2 = get_ram_size((volatile void *)SCB9328_SDRAM_2, SCB9328_SDRAM_2_SIZE); ..... and then: gd->ram_size = size1 + size2 + size3 + size4; > /** > diff --git a/include/configs/scb9328.h b/include/configs/scb9328.h > index 3da214e..c610ed1 100644 > --- a/include/configs/scb9328.h > +++ b/include/configs/scb9328.h > @@ -127,6 +127,9 @@ > #define SCB9328_SDRAM_1 0x08000000 /* SDRAM bank #1 */ > #define SCB9328_SDRAM_1_SIZE 0x01000000 /* 16 MB */ > +#define CONFIG_SYS_SDRAM_BASE SCB9328_SDRAM_1 > +#define CONFIG_SYS_INIT_SP_ADDR SCB9328_SDRAM_1 + 0xf00000 In most boards/processors the stack pointer is set to the internal RAM, that is available before the SDRAM controller is activated. When not available, cache can be used. Is there no internal memory available for this processor ? It could be that the stack is used before the SDRAM is initialized, and then it hangs.

You decide. However, the code in the patch is wrong. If you have only one bank, you could directly simplify your code, I think. > >>> /** >>> diff --git a/include/configs/scb9328.h b/include/configs/scb9328.h >>> index 3da214e..c610ed1 100644 >>> --- a/include/configs/scb9328.h >>> +++ b/include/configs/scb9328.h >>> @@ -127,6 +127,9 @@ >>> #define SCB9328_SDRAM_1 0x08000000 /* SDRAM bank #1 */ >>> #define SCB9328_SDRAM_1_SIZE 0x01000000 /* 16 MB */ >>> +#define CONFIG_SYS_SDRAM_BASE SCB9328_SDRAM_1 >>> +#define CONFIG_SYS_INIT_SP_ADDR SCB9328_SDRAM_1 + 0xf00000 >> >> In most boards/processors the stack pointer is set to the internal RAM, >> that is available before the SDRAM controller is activated.

While I was > trying to solve it I saw some board configs which use sdram, too. Take into account that a lot of new processors set automatically the RAM controller before u-boot is started. I am thinking to the newer i.MX processors, but this is true for other architectures, too. And in some cases u-boot runs as second or third bootloader, such as for at91sam, davinci and omap, without touching the RAM controller that is already programmed by the first-stage bootloader. In your case the SDRAM controller is probably not yet programmed when the stack pointer is set. > Internal RAM came to my mind, too, but I didn't had the time to > investigate further. > > Unfortunately I have to work on another project today and next week and > I think I'm not able to solve the hanging problem.

Fix first the problem to make MAKEALL happy and build the board again.

'include/configs/scb9328.h' is the only file that has to be patched with the patch already send to the ml. 'board/scb9328/config.mk' and 'board/scb9328/scb9328.c' definately need a cleanup, but compilation is ok. The cleanup of those two files 'll be done next week. And hopefully I find some time next week to work on the hangup problem, too. > Best regards, > Stefano Babic > Thanks Torsten ^ permalink raw reply [flat|nested] 6+ messages in thread
