Hi, im trying to run the helloworld application
1st Option: download the hello_world.bin to some location on RAM and execute it
OMAP5912OSK: tftpboot 0x10000000 hello_world.bin OMAP5912OSK: go 0x10000004
This works fine. no problem
2nd Option: I want to burn the hello_world.bin into flash. During startup i want u-boot to launch it after booting - just like the way it boots the kernel.
It does not work for me, this is what i did. $ ../tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x10000000 -e 0x10000004 -n 'Hello Image' -d hello_world.bin.gz hello.img
I downloaded the hello.img and burnt it to 0x40000
I did: setenv bootcmd bootm 0x40000
Now when i restarted the boot i get the following:-
Example expects ABI version 2 Actual U-Boot ABI version 2 Hello World argc = 0 data abort pc : [<10000058>] lr : [<10000048>] sp : 1103fc10 ip : ffffffff fp : 00000001 r10: 110996d8 r9 : 1103fca4 r8 : 1103ffdc r7 : 110996d8 r6 : 00000203 r5 : 00000000 r4 : 00000000 r3 : 00000020 r2 : 00000001 r1 : 0000000a r0 : 00000000 Flags: nZCv IRQs off FIQs off Mode SVC_32 Resetting CPU ...
All i am doing in the hello world example is to read a line and print the line entered.
I am using readline function for doing that.
The programs works fine if i download it to RAM and say go. but if i flash it it does not work?.
Am i missing something?.
