updated linkerscript again..
Hi again,
I was still having strange problems with the version you pulled. I was getting more hard faults due to improperly initialized data section. The older version was working with a printf with no formating (ie printf("hello world");) and as soon as I added some parameters it was hard faulting again.
I ended up replacing the linker script with one based off another template and it seems to work well now. Take a look and pull if you like.
Mark.
Hi, I tried pulling your changes and compiling it, still geting undefined references when linking it. Deleting the references to UARTprintf it compiles fine with the example. Can you please tell me how you link /utils/uartstdio and show me your main file too if possible?
I'll revert the code to my last commit and create a test_newlib branch where we can work on the changes without breaking the last stable build.
Hey scompo. Like the commit says, I removed the UARTstdio entries from LM4F_startup.c you should be able to compile without uartstdio now. when compiling make sure the right newlib is pulled in (defined as LIBM_PATH and LIBC_PATH in your makefile).
Thanks @mroy! Great, I'll make sure it points to the right one. It's ok if I use a test_newlib branch for the moment then merge the branch to main?
I just committed my edits to main.c to make use of the printf and setup the uart. Note that I had to change those lines in the makefile as it tried to include the wrong version for me. The version I used is one I compiled, but the packaged thumb mode newlib should work too.
Are you on irc/freenode someplace? Maybe we could chat.
No worries with where you put it, I just thought you might be interested since I've been banging my head against a wall for 2 days trying to get it to work right
Sure I'm interested, would be really cool to get this working with newLib! I'm on #launchpad-template on freenode right now!
