Strange question but I am using an OMAP 3530 and the boot process currently is from TI's X-Loader to U-Boot to Linux.
What I want is to have two different versions of U-Boot, an extremely optimized and small one (to reduce boot time) but then also a debug version that has a built in device test suite and allows updating of the Linux kernel. The optimized version would boot first and then check if a GPIO is set, if so then it would boot into the debug U-Boot to perform tests or software updates. Anyone do anything like this or is it even possible? Thanks.
