(leanXcam) BF537 uClinux Error

Question asked by skallabrak on Mar 17, 2017
Latest reply on Apr 11, 2017 by Aaronwu

I have a leanXcam(home · scs/leanXcam Wiki · GitHub , SyslogicSystronics AG  ) with a BF537. I had some leanXcams made and I'm currently in the process of trying to load the bootloader and uClinux in to flash.

 

I'm no expert and hardly have experience doing this type of thing, so bare with me.

 

I've successfully managed to load the bootloader into RAM as per https://github.com/scs/leanXcam/wiki/Users-Guide-Using-uClinux#Reload_bootloader_onto_camera and https://docs.blackfin.uclinux.org/doku.php?id=bootloaders:u-boot:loading#wiki-boot_via_the_uart_Bootloaders_U-Boot_loading 

 

Once I've loaded the bootloader in to RAM, and then write it in to flash, I then proceed to load and boot uClinux, and that's where I encounter some issues. 

 

Here's what I see when I boot uClinux, I hope you can point me in the right direction based on this, if not, let me know what else I can include to give you a better idea of what's going on:
