Hello,
I am using the pre-built toolchain gcc-arm-none-eabi-4_6-2012q2 from linaro to compile u-boot (u-boot-linaro-stable) and to compile my standalone applications to run on target(PandaBoard ES rev b2)
hello_world standalone application which comes with u-boot is executing fine on target when I disable CONFIG_SYS_THUMB_BUILD, but when I enable it, target gets reset with following information
How do you build your hello_world? Is it ARM or THUMB?
Panda # go 82000000 hello ## Starting application at 0x82000000 ... undefined instruction pc : [<8200000c>] lr : [<bff83147>] sp : bfeffe40 ip : bfeffc10 fp : 00000000 r10: 00000003 r9 : bffac954 r8 : bfefff68 r7 : bff01d88 r6 : 82000000 r5 : bff01d8c r4 : 00000003 r3 : 82000000 r2 : bff01d8c r1 : bff01d8c r0 : 00000002 Flags: nzCv IRQs off FIQs off Mode SVC_32 Resetting CPU ...
