- Bcc:
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.
