[U-Boot-Users] Execution problem in MIPS based...
Hi, I am trying to add some POST tests in the uboot for MIPS 32 based board.Asthe number of tests increases i face some problems.The uboot strucks at some point.I am using the cmdline options to execute each tests.If i add eg some 5 tests it works fine.If i add one more then the processor hangs.I am including some c files from outside.All the tests works fine individually in uboot using command line option.If i build with all the tests, one or the other makes the system hang. I tried to debug and the statement causing the Rom Exception is 8003CAC8 0x3C1C0003 lui $gp,0x0003 in the begining of one of the functions. Please give me some pointers
Is there any size limitation to uboot?
Thanks in advance, Suresh

Is there a watchdog on your system?

Disable the watchdog?

You should know your hardware better than us. Check the documentation and schematics.
