JN5168, eclipse and atof

shauntaylor — Tue, 16 Aug 2016 15:39:22 GMT

In having an issue with eclipse and atof (atoi and atol work fine).

I have a number of products which were developed for the JN5148 using eclipse. I have been moving them over to the 5168 as required and have not had an issue until now - this is the first code which has used string to number conversion.

The descriptions of the problems are:

/ba-tools/b-gcc/ba-elf/ba2/newlib/libc/sys/basim/../../../../../../../gcc-4.1.2-ba-r8352/newlib/libc/sys/basim/glue.c undefined reference to `_end' line 129 C/C++ Problem

/ba-tools/b-gcc/ba-elf/ba2/newlib/libc/sys/basim/../../../../../../../gcc-4.1.2-ba-r8352/newlib/libc/sys/basim/glue.c undefined reference to `_stack' line 129 C/C++ Problem

Has anybody hit this snag before and fixed it?

Did you get to the bottom of this?

Oddly my environment was working and stopped.

No not yet, I've had to put this aside for a few days.

To let you know, I fixed it on my system by modifying AppBuildEnd_JN5168.ld down under c:\Jennic

Added an entry in .bss before the close } as

_end = (.)

Then in .stack, added a line before the close } as

_stack = (.)

Found these in other forum elsewhere for other MCU. Everything appears to work ok. Have a pretty involved firmware and no issues.

Many thanks David - works for me.

I was just about to pick the issue up again and there was your reply. Great timing!
