OSE EPSILON on MAC7100 exactly MAC7111 LCEVB

I'm making some test with a Freescale MAC7111 on a MAC7100LCEVB. I use IAR as compiler and OSE EPSILON as RTOS. Now I have a project that is compiled righ, but when I upload the firmware to the MAC7111 the program doesn't exit from vector table initalization on CRT0.s79 someone have some idea?

;------------------------------------------------------------------------------ ;- Setup Exception Vectors in Internal RAM before Remap ;------------------------------------------------------ ;- That's important to perform this operation before Remap in order to guarantee ;- that the core has valid vectors at any time during the remap operation. ;- Note: There are only 5 offsets as the vectoring is used. ;- ICE note : In this code only the start address value is changed if you use ;- without Semihosting. ;- Before Remap the internal RAM it's 0x300000 ;- After Remap the internal RAM it's 0x000000 ;- Remap it's already executed it's no possible to write to

0x300000. ;------------------------------------------------------------------------------ ;- Copy the ARM exception vectors

ldr r13,=ZZ_SVC_STACK ; Don't depend on SP being OK at this stage stmfd sp!, {r6-r7} ; CSTARTUP saves addresses here mov r8,#0x0 adr r9, VectorTable ldmia r9!, {r0-r7} ; read 8 vectors stmia r8!, {r0-r7} ; store them ldmia r9!, {r0-r5} ; read 5 absolute handler addresses stmia r8!, {r0-r5} ; store them ldmfd sp!, {r6-r7} ; Restore addresses used by CSTART

Best regards.

This is just a stab in the dark, but IIRC the MAC7111 ARM cores are configured to be big endian, while most of the other vendors who use the ARM core configures it to little endian. Hence the default for most ARM compilers are little endian and one has to explicitly use an option to compile for big endian.

Yes it's right what you say, but I have set my IAR as big endian and OSE Epsilon to big endian. The board doesn't run anyway. I also tryed with the last IAR 4.40a but noting too.

Best regards.
