ASM51

Prebuilt toolchain para usar com placas ARM com processador antigo ( exemplo: mini2440 da FriendlyARM).

Eu não encontrei gcc novo para uso com esse modelo de processador, então compilei essa. Nas minhas aplicações funcionaram.

Segue o link para download:

Palavras chave: gcc toolchain mini2440 armv4t prebuilt binary

Prebuilt toolchain for use in x86_64-linux

gcc version: 9.2.0

Target:
armv4t with kernel 2.6.32
Example board: mini2440

Creatte using crosstol-ng

How use:
0) download

1) extract:
tar -xf gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabi.tar.xz

2) setup path
export PATH=$PATH:/path/gcc-mcut-9.2.0-linux-2.6.32-armv4t-softfp/arm-mcut-linux-gnueabi/bin/

3) create a test file:
nano main.cpp
#include <stdio.h>

int main()
{

#ifdef __GNUC__
fprintf(stdout,"Crosstool test\nTest compiler\nVersion: %d %d %d\n",__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__);
#else
fprintf(stdout,"Teste\n");
#endif

return 0;
}

4) compile:
arm-mcut-linux-gnueabi-gcc main.cpp -static

5) check:
readelf -A a.out

File is armv4t format.
Attribute Section: aeabi
