[How To] Make Booster's IPL SDK work with GCC > 4.0.2

[ab5000]

Hi.
Today i was experimenting with Booster's IPL SDK and my IPL wasn't working, even if it compiled correctly.
Searching in this forum i found that the IPL SDK doesn't work with a GCC version highter than 4.0.2. I found a solution to this problem, so i wrote this short How To.

The solution is deleting optimize (-O) flags from the Makefile, cleaning all the O files and recompiling.
Open your Makefile and find the CFLAGS line. It looks like this:

CFLAGS = -O2 -G0 -Wall

Now disable optimization (-O flags). The CFLAGS line without optimizations looks like this:

CFLAGS = -G0 -Wall

Now do a make clean.
If you previously compiled with a Makefile with optimization flags, you'll need to clear all IPL SDK .o files.
So delete all the .o files from these folders:

IPL_SDK
LIBC
tff

Now you're done. Just compile your IPL.

Bye!

The IPL prepared with sdk is working on Slim devices?

thx to share this. I was obliged to recompile with a older gcc to have it working
would be interresting to compare the assembler generatedwith and without
optimization to see where the code breaks

I have a question.

I have MinPSPW + DevC++. I've tried to compile Flash Led sample.
I've got an error:

Code: Select all

Assembler messages:
line numbers must be positive; line number 0 rejected

but it creates pspboot.bin anyway. So I can just ignore this error?

Yes, you can ignore it.
