Re: [microblaze-uclinux] Spartan 3, uClinux problems

Hi Lancer,


Hi John, and thanks for your patience ;-)


Have you selected the "ROM" model in the kernel configuration (Processor
Type and Featuers -> Memory Model)?


No...I've selected RAM


This should default to leaving the filesystem in flash.  If you look at
drivers/mtd/maps/mb_auto.c - you can see the handling required in an MTD
mapping driver for the CONFIG_MODEL_ROM option.  Basically:

#ifdef CONFIG_MODEL_RAM
         romfs_loc = &_ebss;
#endif
#ifdef CONFIG_MODEL_ROM
         romfs_loc = &__bss_lma;
#endif

We should also fold this change into the generic uclinux.c mapping
driver - I will add a ticket to cover this for a future peatlinux release.



...so I have to select "ROM" model in the kernel configuration, isn't it?

Regards

Lancer
