unhosted baremetal boot

[Altera_Forum]

Hello, 

I'm tring to boot a baremetal application from uboot. I linked my application with a script like the one in examples (altera-socfpga-hosted.ld) whith following modifications: line 23: GROUP(-lgcc -lc -lcs3 -lcs3hosted -lcs3arm) to GROUP(-lgcc -lc -lcs3 -lcs3unhosted -lcs3arm) and line 28: ram (rwx) : ORIGIN = 0x02000000, LENGTH = 32M  ram (rwx) : ORIGIN = 0x01000000, LENGTH = 32M running the application from debugger all works fine. When I try to run the application from u-boot with the following commands:  fatload mmc 0:2 0x01000000 myApp.bin  go 0x01000000 or  go 0x01000040  the command fail with this error:  # # Starting application at 0x01000000 ... data abort   MAYBE you should read doc/README.arm-unaligned-accesses  pc : [<3ff8223c>] lr : [<01000198>] sp : 3ff4f63c ip : 00000083 fp : 00000000 r10: 00000002 r9 : 00000000 r8 : 3ff4ff60 r7 : 3ffbb8c4 r6 : 01000000 r5 : 3ff505fc r4 : 00000002 r3 : 01000000 r2 : 3ff505fc r1 : 010001d0 r0 : 60000153 Flags: nZCv IRQs off FIQs off Mode SVC_32 Resetting CPU ...   running a readelf in a linux shell the result is: readelf -h myApp.elf ELF Header:  Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00  Class: ELF32  Data: 2's complement, little endian  Version: 1 (current)  OS/ABI: UNIX - System V  ABI Version: 0  Type: EXEC (Executable file)  Machine: ARM  Version: 0x1  Entry point address: 0x1000040  Start of program headers: 52 (bytes into file)  Start of section headers: 399332 (bytes into file)  Flags: 0x5000002, has entry point, Version5 EABI  Size of this header: 52 (bytes)  Size of program headers: 32 (bytes)  Number of program headers: 2  Size of section headers: 40 (bytes)  Number of section headers: 20  Section header string table index: 17   What is wrong?  Thank you  Nicola
