[U-Boot-Users] Booting vxworks image from U-boot

[Zvika Vered]

Hello,

 

Is it possible to boot a vxworks ELF image using 'bootvx' ?

I downloaded a vxworks 6.3 ELF image using 'tftpboot' and launched 'vxboot'.

U-boot crashed.

The vxworks ELF image is OK. When I download it using JTAG after reset it works.

 

What is the best way to boot vxworks ELF image from U-boot 1.3.2 prompt ?

 

Thanks,

Zvika Vered

You have JTAG ICE connected, then debug it. How crash, what's the CPU
status, what kind of exception happens, etc.

I'm just wondering, how about changing tftp download address that
cannot be bss cleared by VxWorks? Simply, near the top of RAM?
