It will just copy the image from the flash to the RAM and gives a jump to the predefined location. We were able to load any image built using ARM SDT 2.51 and multi-ICE. But we are not able to load the eCOS generated with RAM boot option. I am using cygwin, binutils 2.10, gcc 2.95.2 on Windows platform. Is it possible to use such kind of boot loader for eCos?

Probably. For a start, are you sure you are in supervisor mode when execution is transferred. Secondly, disable CYGSEM_HAL_USE_ROM_MONITOR. Finally check your entry point - it should be reset_vector. After that - well, if you've got an ICE you should be able to debug it pretty well. Jifl -- Red Hat, Rustat House, Clifton Road, Cambridge, UK.

The boot loader for ARM 7TDMI based SOC board. With a jump to a predefined location my boot loader should start the execution of the program, but it is not happening. I have given a jump to vectors location. I tried with both the binary and elf images at 0x0, 0x1000 locations of the RAM. But it is not working. What will be the problem??? Is there any other way to execute the program on my ARM7 TDMI based SOC board???. If so, please help me . I am using gcc compiler cross compiled for ARM processor (arm-elf-gcc, arm-elf-ld, arm-elf-objdump, arm-elf-objcopy etc) on windows Host using eCos as Operating System.

If you have changed the startup location in the ecos.ecc as flash, you need to provide the memory configuration of your board in the .ldi files in the pkgconf directory of arm. see to it that the changes are reflected in the header files (mlt_arm_pid_rom.h, mlt_arm_pid_ram.h). > I have given a jump to vectors location.

This method holds good as long as you are using manual configuration tool on linux. on windows you can do the changes on the memory layout window. ^ permalink raw reply [flat|nested] 10+ messages in thread
