| Post subject: | Atmel u-boot port: Missing CONFIG_JFFS2_CMDLINE support |
Hi there, Has anyone else noticed certain functionality missing for the Atmel u-boot port? For example, you can't compile with options: CONFIG_JFFS2_CMDLINE CONFIG_CMD_JFFS2 I need these defines to use do_jffs2_fsload, but enabling them causes a bunch of errors, i think because flash.c hasn't been ported for any of the Atmel boards. Also functions like ioremap and virt_to_phys haven't been implemented in u-boot. Has anyone had similar problems and found ways around implementing these functions, or is it just a case that these need implementing. |

To which version of U-Boot are you referring? please_work wrote: Also functions like ioremap and virt_to_phys haven't been implemented in u-boot. The last time I looked at U-Boot, it didn't use virtual memory. So there is no need for those functions in U-Boot. Regards |

I think i partly answered my own question, its actually NOR flash that has not been implemented, and why it complains when building. I had to add the following defines/undefines to my board.h: #define CONFIG_JFFS2_NAND 1 #define CONFIG_JFFS2_CMDLINE 1 #define CONFIG_CMD_JFFS2 1 // Required to include cmd_jffs2.c #undef CONFIG_CMD_FLASH /* NOR flash, if populated */ #define CFG_NO_FLASH 1 // No NOR flash is preset Thanks for you reply blue_z, i couldn't really see a flash.c in any of the Atmel boards, which is why i generalized (also i'm using 1.3.4). As for the remapping, i'm trying to port functionality from an older version of u-boot ported for a Samsung s3c2412, which made using of ioremap and virt_to_phys, which what made me think they were missing. But i'll take another look at it, thanks for the help! |
