Hello:
I've downloaded and compiled U-boot with buildroot for AT91sam9x35ek using NANDFlash, and managed to get into console (after kernel load) with an *.ubi RFS; but Im working in a project that has a RFS in jffs2 format(old project started at 2011, RFS produced by Tool only in that format with custom libraries i can't touch), basically i must use jffs2. I am trying to make kernel linux4sam_5.6 boot into the same RFS but jffs2 format(also compiled by buildroot), this RFS is for testing, an empty skeleton. I tried changing bootargs several times copying from different websites but I'm failing. Can you please help me hoy can i modify these BOOTARGS for them to work with *.jffs2 NandFlash for AT91sam9x35. Before you ask, i have read U-boot manuals commands, how mtdparts works, i cant find how to address my root="" boot arg clear enough to understand it. I'll paste the ubi bootargs so you can explain me how to change them for jffs2.
#define CONFIG_BOOTARGS \ "console=ttyS0,115200 earlyprintk " \ "mtdparts=atmel_nand:256k(bootstrap)ro,512k(uboot)ro," \ "256k(env),256k(env_redundant),256k(spare)," \ "512k(dtb),6M(kernel)ro,-(rootfs) " \ "rootfstype=ubifs ubi.mtd=7 root=ubi0:rootfs rw" #endif
