HI, ARM experts, I met a question. When I would like to build code with tool-chain aarch64 for CPU cortex-a55, it existed the following compiled error messages. Could someone can give me some suggestions. Thanks. /usr/bin/aarch64-linux-gnu-gcc test.c -o test.adx -mcpu=cortex-a55cc1: error: unknown value ‘cortex-a55’ for -mcpucc1: note: valid arguments are: cortex-a35 cortex-a53 cortex-a57 cortex-a72 cortex-a73 thunderx thunderxt88p1 thunderxt88 thunderxt81 thunderxt83 xgene1 falkor qdf24xx exynos-m1 thunderx2t99p1 vulcan thunderx2t99 cortex-a57.cortex-a53 cortex-a72.cortex-a53 cortex-a73.cortex-a35 cortex-a73.cortex-a53 generic; did you mean ‘cortex-a35’?
It's my pleasure to learn here.

Hi, i want to know if i learn the basic arm assembly language, will it run on any arm processor? As i read in architecture reference it says every new cpu builds on fellow cpu instructions. I want to develop software on arm devices, so is it good to know its assembly or instead i have to learn c/c++? I cant find answer to this question on my own, even HL language build on assembly, why to choose HL over ASM? I know if it build on ARM it will not work on x86, but HL langs are not build on ARM's assembly which i think decrease performance. I have only beginner level education on c++, i would like your guideness. Btw Community portal a little bit complicated, i couldnt find a place to ask this question. Thanks
Thank you for answering. I will ask the question on the forum.
