wolfSSL has ARMv8-A assembly implementations of some functions for
both A64 and A32 ISAs. However, some of the A32 versions use r11,
which is usually not allowed:
wolfcrypt/src/port/arm/armv8-aes.c: In function 'wc_AesCbcEncrypt':
wolfcrypt/src/port/arm/armv8-aes.c:3303:5: error: fp cannot be used in 'asm' here
3303 | }
| ^
That can be fixed by adding the compiler flag -fomit-frame-pointer,
but then there is another failure:
/tmp/ccV19DQV.s: Assembler messages:
/tmp/ccV19DQV.s:248: Error: first transfer register must be even -- `ldrd r11,r10,[r14,#4*14]'
make[3]: *** [Makefile:5858: wolfcrypt/src/port/arm/src_libwolfssl_la-armv8-chacha.lo] Error 1
This is definitely not a valid instruction in A32, which suggests that
this code isn't being tested at all upstream. So disable it here.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
