You link eCos directly with your application to give you the executable. I recommend you read the Getting Started guide in the documentation to get familiar with the principles. > also when we compile our applications what will be the name of the > executable, will it have a .axf extension? No. GCC cannot generate ARM executable format binaries, although they are very similar to the ELF format binaries GCC does generate. Someone may already have written a conversion tool - I'd be interested to know if they have. Jifl -- Red Hat, Rustat House, Clifton Road, Cambridge, UK.

I am trying to compile a simple C code for my arm processor IXDP425. the contents of my_file.c which i wish to run on the arm processor is /* this is a simple hello world program */ #include <stdio.h> int main(void) { printf("Hello, eCos world!\n"); return 0; } the steps that i follow are as listed below. 1. make (the Makefile was already present in the directory) 2. arm-elf-objcopy -O srec my_file my_file.srec this gives me my_file.srec 3. after that i try to load this file using redboot (launched from minicom) by giving the folowing command Redboot> load -v -m yModem 4. then i transfer my_file.srec using the Y MODEM protocol. the file gets transferred. When the transfer is complete, i get a sound from the IXDP425 and the following message RedBoot> load -v -m yMODEM Entry point: 0x00080040, address range: 0x00080000-0x0008868c xyzModem - CRC mode, 777(SOH)/0(STX)/0(CAN) packets, 11 retries 5. thwn when i type go, i get the following error RedBoot> go $T050f:00080044;0d:0ffd0fec;#1b on pressing any key, the garbage string gets repeated RedBoot> go $T050f:00080044;0d:0ffd0fec;#1b$T050f:00080044;0d:0ffd0fec;#1b$T050f:00080044;0 Can anyone tell me what should i do?
