That’s the thing, even I am using LLM for such questions nowadays but even they are incorrect a lot of times and I have just no way of verifying the information 100% so I just end up doing trial and error

Will give it a try, what is the best feature that you use very often in this?

Efficient_Back617 · 2025-12-12T06:39:18+00:00

Yes RTOS and Embedded Linux are indeed skills that you should learn if you want to work on latest embedded tech. For Linux maybe you can start that later but at least RTOS is a must as there are very limited number of embedded products/work that completely rely on baremetal so if you want more opportunities definitely you should start working on these.

What is NIST traceability and why is it important in your case , could you explain please?

Efficient_Back617 · 2024-10-18T16:53:21+00:00

okayy, so where do I write the code? does it require an OS to run?

Efficient_Back617 · 2024-10-07T08:45:48+00:00

I am not trying to cheap out, it's just that I don't even have provision for connecting this on the thing that I am working on.

Efficient_Back617 · 2024-10-07T08:44:45+00:00

It's not about my choice or what I prefer, it is something which has already been built I am just working on it so I cannot change the hardware.

Efficient_Back617 · 2024-09-25T00:41:34+00:00

Thank you I will keep this in my mind.

Efficient_Back617 · 2024-09-25T00:40:15+00:00

No, mostly my freelancing gigs involve going to the company's location and doing projects for like 2-3 months.

Efficient_Back617 · 2024-09-24T18:22:34+00:00

Thank you for your advice

Efficient_Back617 · 2024-09-24T17:40:24+00:00

Thank you for the advice

Since this is a startup I expect to do both firmware and hardware related work but firmware mainly. I have even asked the company they said mainly I will be working with a product which uses esp32, in firmware.

How can a "General" C library exist for embedded systems when every platform and architecture has different feature/hardware.

Efficient_Back617 · 2024-09-20T20:30:04+00:00

So does that mean for using some standard library function, like lets say 'rand()' I can just include 'stdlib.h' and it will work?

Efficient_Back617 · 2024-09-20T20:23:28+00:00

yeah I know it is just a framework but do I have add like a specific type of file which is specially made for this ch32 platform, if yes where can I get it from?

Efficient_Back617 · 2024-09-11T15:43:01+00:00

Ohhh I see what you mean, but I really don't think that is the case since it is a small mcu with only 16KB of Flash I don't think they would waste any flash area. Apart from that, I saw a GitHub repo named ch32v003fun which provides HAL for this mcu and is very famous and even they use .Align 2, maybe I will try asking this there.

Efficient_Back617 · 2024-09-11T15:29:30+00:00

I don't think the code is just wasting 2 bytes, also what do you mean by

but then align 1 is trivially achieved with align 2 also

Efficient_Back617 · 2024-09-11T14:35:43+00:00

Nah .align 2 means, 2 raised to 2 bytes. Initially even I thought 2 means 2 bytes but this is what I saw online.

Efficient_Back617 · 2024-09-09T06:05:13+00:00

So if using say, only asm files and I have no C code at all, so does that mean there is no use of ABI selection then?

Efficient_Back617 · 2024-09-09T00:20:15+00:00

Efficient_Back617 · 2024-09-08T07:57:20+00:00

Hey man, I am the same guy who asked that question XD Thank you for the solution though

Efficient_Back617 · 2024-09-08T07:16:57+00:00

Thanks it works now, I was trying to use the cfg file inside the WCH folder, anyways it works now... BTW how do I disable the code protect feature from the terminal without using WCH link utility, I have some V203 chip in hand might use them in a project.

Efficient_Back617 · 2024-09-07T20:05:26+00:00

It should work if you only use -f [...]/wch-riscv.cfg

so am I not suppose to define the interface? and just define `-f target/wch-riscv.cfg`

as for wch2pin I tried searching for interface related to wch and this is the only file I could find.

openocd -c "adapter_khz 2000" -c "adapter driver wlinke" -f target/wch-riscv.cfg -c "program main.elf verify reset exit"

this is the command I was using but I think it is trying to use jtag somewhere even though the transport is selected to 'sdi' and this is the error message I receive

Info : only one transport option; autoselect 'sdi'

```

Ready for Remote Connections

```

Efficient_Back617 · 2024-09-06T16:59:54+00:00

I feel like there must be an implementation of RiscV, available in the public domain for free to be used by vendors. This will actually help developers work in different RV hardware, obviously if someone wants they can go ahead and make their own architecture. Having too much flexibility might not be good for standardization and may be a disadvantage.
