2010-11-02 05:28:11     CM-BF561 based uBoot config

Steven Mattheussen (BELGIUM)

Message: 95478   




I am relatively new to customizing uBoot. I want to build uBoot for my modified board for the Bluetechnix CM-BF561 module, but I am not sure if I'm doing it correctly. The hardware includes two Omnivision OV2655 camera's and and the PLX NET2272 USB 2.0 controller. I don't want to use the ethernet module, so I commented the following settings in u-boot/include/configs/cm-bf561.h and tried to compile.



* Network Settings


/* #define ADI_CMDS_NETWORK     1 */

/* #define CONFIG_NET_MULTI */

/* #define CONFIG_SMC911X               1 */

/* #define CONFIG_SMC911X_BASE  0x24008000 *//* AMS1 */

/* #define CONFIG_SMC911X_16_BIT */

/* #define CONFIG_HOSTNAME              cm-bf561 */

/* Uncomment next line to use fixed MAC address */

/* #define CONFIG_ETHADDR       02:80:ad:20:31:cf */


Now it gives the following error:


bfin-uclinux-ldr: Punching holes beyond the end of an LDR is not supported


This is 'solved' by commenting out




But I am not sure this is what I want, from what I read BFIN_BOOT_PARA (the default and only bootmode for the CM-BF561) and CONFIG_ENV_IS_EMBEDDED_IN_LDR are somewhat connected together.


Essentially I want to load uBoot via UART and then either upgrade uBoot or flash uBoot over the Blacksheep bootloader. Can someone help me find the correct settings?


Thanks in advance!

What's the version for your u-boot? I tried this on the trunk ,version 2479, commented out the networking setting code and there is no compilling error.

as documented in the wiki and in the hardware manuals, the BF561 does not support uart boot.


as for upgrading via Blacksheep, you'll have to talk to the bluetechnix guys and/or review the Blacksheep manuals.  that is not an open source project, nor do we support it in any way here.


as Aaron suggested, only the u-boot source as attained from this project is supported here.  that means files from:




if you are getting source code from any other location, then you'll have to seek support from them.  most likely you'll need to contact bluetechnix.
