[ECOS] Getting RedBoot[ROM] into the Phytec PhyCORE-MPC555

[Dragos Carp]

Hi Miguel,

Unfortunately I have no experience with CodeWarrior's flash programmer 
(I use only GNU tools and a custom BDM interface), my Redboot is 
programmed in external flash (dual mapped to address 0x00). During 
development process, because of the inconvenient update, I donÂ’t intend 
to write it in internal flash.

Regarding your .srec load problem, I wonder if the CodeWarrior's flash 
programmer is able to interpret the .srec file, actually this is a human 
readable text file. Normally you should write in the internal flash just 
a binary representation from your .elf file (see powerpc-eabi-objcopy 
“–O binary” option).

If IÂ’ll need to write into the internal flash, my first attempt will be 
to write a small program, which uses PhytecÂ’s supplied routine for 
writing into the internal flash. This program and the binary image, both 
loaded in moduleÂ’s RAM, should do the job.

Best regards,

Dragos
