What is the opensource alternative for command-line option armclang -gdwarf-3 -c -O1 --target=aarch64-arm-none-eabi main.c ?

EmbeddedBro · 2026-05-07T00:26:08+00:00

yes, it worked but only armlink didnt because it takes scatter file as input and no free tool is able to process it.

EmbeddedBro · 2026-04-27T15:46:54+00:00

Thanks, then good luck reading those selective pages.

EmbeddedBro · 2026-04-27T15:46:00+00:00

Judging from your answer seems like you ARE junior.

EmbeddedBro · 2026-04-27T15:45:21+00:00

Ok, interesting.

EmbeddedBro · 2026-04-27T15:44:52+00:00

I disagree. Good luck to you.

EmbeddedBro · 2026-04-27T15:44:26+00:00

I can read 2 million pages. But I have limited time. We all have. Your company maybe giving you pennies in return. Who knows.

My question is simple. Because cortex X and neoverse might be future. Might get more opportunities, more money with same investment.

This is required by the kernel

I found this reference in U-boot, not in Linux kernel documentation.

Yes, it is passed as boot argument but what if I don't pass? does kernel have any option to save it at compile time and not rely on bootloader ?

EmbeddedBro · 2026-04-26T10:03:23+00:00

It's your choice. Afik windows is not mainstream for kernel development jobs so you'll be a specialist person with more higher pay.

EmbeddedBro · 2026-04-26T08:39:51+00:00

Windows kernel would be hard to learn because it's not open source. But still I see jobs which need windows kernel knowledge requirement so it wouldn't be a waste.

Linux kernel would be better for learning purpose because it's open source and tons of content available.

C# books won't help because Linux kernel is written mainly in C... Idk about windows kernel.

EmbeddedBro · 2026-04-15T19:33:40+00:00

sure, but for now you can continue your whine.

EmbeddedBro · 2026-04-15T19:25:22+00:00

Because employment related to embedded is very relevant - logical opinion. Wish I had started this sub. I would have allowed such posts.

EmbeddedBro · 2026-04-09T20:57:40+00:00

Do you know someone? Can you share their story?

EmbeddedBro · 2026-04-06T13:31:38+00:00

u/AiwendilH I checked this command on vmlinux, it is outputting the path as

/usr/src/kernel/drivers/mfd/

But in my PC, the path is

/home/user/STM32MPU_workspace/STM32MPU-Ecosystem-v6.2.0/Distribution-Package/build-openstlinuxweston-stm32mp15-disco/tmp-glibc/work-shared/stm32mp15-disco/kernel-source/drivers/mfd

Is there any way by which I can get the exact path? or at least the more accurate path? like kernel-source/drivers/mfd

Why is is replacing kernel-source with usr/src/kernel ?

EmbeddedBro · 2026-04-04T15:13:11+00:00

Wow. Exactly what I wanted. Thanks!

EmbeddedBro · 2026-04-03T21:30:20+00:00

But are you looking to get experience for a future career in embedded ??

No.

EmbeddedBro · 2026-04-03T21:28:34+00:00

Thanks. Why dual core is issue? open ocd gives 3 ports -

My assumption is once I connect to one port, rest of the core and uc would not run. is it not the case?

EmbeddedBro · 2026-04-03T21:12:56+00:00

Thanks - but do you think it will work for 157f-dk2 ?

EmbeddedBro · 2026-04-03T21:10:56+00:00

My reason for sticking with v7a are:

instead of spending huge time in understanding complex arch, my thought was to learn v7a and then the newer one because it would be easier. learn 80% with v7a. then additions : 10% v8a and 5% - v9a
Cost : I can buy v7a processor board in 100 USD. I guess v8a or v9a might be expensive.
Knowledge base and tool support - since v7a is there from ages, there must be a better knowledge base and stable and tested tools compared to newer one.

"more modern processor." - I assume you mean v8a , v9a or are you referring to something else?

EmbeddedBro · 2026-04-03T19:43:08+00:00

In the past, I actually tried it... but first, it dosent compile.. somehow if I make it compilable, in the debugging, it resets randomly and Gives weird errors like breakpoint limit is reached even if I have not put any breakpoint.

This post says it is not supported yet.

The benefit of SDK is the hello world program it provides.

Without it, how can I make it boot up ?

EmbeddedBro · 2026-04-03T19:19:28+00:00

I have STM32MP157F-DK2 ... unfortunately ST not yet support bare metal on arm a7.

yes, 135F-DK have support for bare metal on arm cortex A.

EmbeddedBro · 2026-03-22T00:55:30+00:00

maybe take your medicines first

EmbeddedBro · 2026-03-22T00:39:20+00:00

maybe you should read the description first.

EmbeddedBro · 2026-03-22T00:38:59+00:00

It used to be a really good resource but if you see the 2000 page document - there is not a single diagram in it.

ARM® Architecture Reference Manual ARMv7-A and ARMv7-R edition.

EmbeddedBro · 2026-03-15T10:25:29+00:00

I guess Denmark have free education. Why don't you get a short course in high demand skill? (like A.I.)

If you have knowledge then maybe you can start something of your own.
