Dear Friends,

I'm bringing up a custom i.MX28 based board.  I'm having trouble bringing up the u-boot (version v2013.04) loader.  The > > Powersupply has been design as detailed in section 4.1.2.1 (VDD5V source only) of application note AN4199:

http://www.freescale.com/files/32bit/doc/app_note/AN4199.pdf I am referring Patch L2.6.35_10.12_SDK_5V_SUPPLY_PATCH.tar.gz at freescale website which is for bootlets with VDD5V > only support. I have even applied the patch to bootlet code imx-bootlets-src-10.12.01.tar.gz which is working fine. Based on the bootlet patch, I have modified the u-boot code but I couldn't able to boot. Please find the u-boot patch at > http://pastebin.com/VudxqTHQ Can anyone please review it and share what is missing in the patch? Regards, Ankur

I am struggling to run u-boot spl with VDD5v. Please share if you need any debug information to analyse?

Regards, Ankur.
