I'm bringing up a custom i.MX283 based board. I'm having trouble with random lockups anywhere from 1 or 2 seconds to several minutes after applying power. I believe the issue is power related. I've implemented the design detailed in section 22.214.171.124 (VDD5V source only) of application note AN4199:
After researching the problem I came across this patch on the Freescale website:
Currently, I'm using mainline kernel version 3.8.3 with u-boot version v2012.10.
Are the fixes described in the bootlet patch implemented in mainline u-boot? Can u-boot be configured for VDD5V only? I've looked into the u-boot and bootlet code, but the code is seemingly quite different...
