Hi,

I am using the u-boot version 2011 patch level 09 . When i booting the u-boot through JTAG i am getting following :

Hi,

Have a look at this link http://beagleboard.org/challenge which is discussing the same issue.

Hi Prabhakar,

WE are designing a project based on omap3530.We have code composer studio v5.1.we are working with beagle board rev C5 as a reference.On beagle board,we are

able to download u-boot ELF file through JTAG and it is successfully ( if board having x-loader). Now as we are trying to download x-loader ELF file through

JTAG.But it is not working.

our prototype board don't have any mmc card interface. So, we have to load x-loader through JTAG or USB only.

Is it possible to download x-loader through JTAG?

As OMAP3530 supports USB booting can we boot x-loader and u-boot through USB.Because, We are able to boot kernel and file system through USB

insted of mmc card ( may be because of u-boot usb drivers).

please help..

Thank You

No idea through JTAG interface but looks like you can do it through USB have a look at this link

Yes it is possible to boot using by loading x-loader ELF file to memory and then u-boot. I remember I tried doing this during bringup of one of OMAP3530 family of device and it worked for me.

Try doing step-by-step execution and see what exactly going on there? I suspect something wrong with prcm_init funtion, put a break point there and see if you find something.

Thanks,

Vaibhav
