 |
|
Or is cross compiling the only option?
| Code: |
$ git checkout v2.10.0
HEAD is now at b6c094840 Merge "docs(changelog): changelog for v2.10 release" into integration
$ git rev-parse --short HEAD

$ git clean -dxf
$ make PLAT=rk3399 CC=gcc HOSTCC=gcc

| This seem to be related to the rk3399 as I tried the same on a Pi5 with "make PLAT=rpi4 CC=gcc HOSTCC=gcc" (as there is no rpi5 defined yet) and it resulted in a build/rpi4/release/bl31.bin. |

pgu,
you will need to share more context if you need help. It is unclear what repo you are using. the error "make[1]: arm-none-eabi-gcc: No such file or directory" seems indicate something is missing but without context there is no way to understand what it is. |

| Your output suggests to me that cross-compiling is at least somewhat supported, since it tried to use a qualified gcc name. You have no such gcc. If you install the required gcc, what happens? |

It seems like I need a cross compiler for the cortex-m0. If I try to use the regular arm gcc on the host I get an error that the thumb/float-abi=soft is not supported:

Your regular gcc seems to build for aarch64(arm64) so my guess is that you do need cross-compile. |
