Re: ecos for ATLAS (MIPS 4Kc)


Hi all,

After a year I am back to work on the MIPS atlas port for my personal Atlas board.

I pulled the ecos source from the CVR repository using ecos as Tag.

I feel that some things have changed drastically. I tried building the example code (hello.c).

Problems I faced:

1. Compilation error with the math lib files.
Workaround: I disabled the Math library to get passed this.

2. Linker options ?fatal-warnings not recognized by ld.
Workaround: I changed ?-WI, ?fatal-warnings? to ?-WI?.... This option is under infra build options >> Additional linker flags.


3. When I ran the hello example program (with the terminal utility connected to the Serial0 & Serial1 at 115200 bauds).

Observation: Serial0: sent a GDB packet, & Serial1: nothing

When I looked at the build options under ecos HAL >> MIPS architecture >> Atlas eval board >> no of comm channels on the board == 1.

I would think it to be 2. Why?

ecos HAL >> MIPS architecture >> Atlas eval board >> Debug serial port & Diagnostic serial port are both configured to be 0.

Note: In the past I have seen printf?s sending stuff though one of the Serial ports.


Does somebody have an explanation for these changes that I see? Or did I use the wrong tag (?ecos?) to pull the source?



Thanks a lot, -Mike.
