I am new to ARM and due to some other development requirements, I am required to migrate from W10 to Linux. I am learning ARM dev using STM32F103 using Kiel and STMcubeMX. I want to know what are my options on Linux.
Posted this in /r/embedded and then found this subreddit and thought I'd ask here.
I've been wanting to get into Cortex for a while but get overwhelmed by the options whenever I start shopping. Is there a resource that can help find the right board for somebody?
I found Joseph Yiu's ARM Cortex-M for Beginners somewhat helpful, but it's almost 4 years old by now.
After cracking open a firewall I found a mpci slot. Now I'm wondering what I could do with this. I think normally this would hold a wifi card depending on the model.
Question is, is there a way to see what all could be supported on this mpci slot? I don't know much about arm and I *think* it would require seeing the device tree file. Is that correct and if so is there a chance a mortal could add to it (the device tree) assuming the kernel had a driver?
To be clear I'm basically a x86 guy.
I still had that vasco 835 digipass with a nice display and keyboard so I thought of reusing it. Since the parts are all very delicately soldered I thought perhaps it would be better to reflash the mp who controls it. I have never done that before, though read a lot of threads about it.
My steps so would be:
My general experience in this field is using arduino for quite some time, I'm a backend dev with java/ and a bit of c++ background and everything you need for arduino. As well I'm familiar with electronics.
Gear which might be of importance:
I will make some general assumptions throughout this thread.

Until recently, modern browsers annoyed the heck out of me on my Miix 630 from Lenovo. Chrome is not available, Edge is hardly working at all and Firefox Nightly had serious problems with stability and video playback. Now I downloaded the ARM version from Microsofts new Edge Chromium Beta build for ARM devices and its working super fast. Its snappy. Like I can forget the old Snapdragon 835 working in my machine. Awesome. ARM is taking some serious steps forward.
Noob warning here.
Sorry about this.
Very curious to how is it that Raspbian is shipped with the Raspberry Pi.
Didn't this require to build Linux from scratch so that it can run on a different instruction set/cpu/architecture?
Very confused about this especially since to my (rather limited) understanding, the Linux Kernel is written in C (which, again, to the best of my knowledge, was compiled specifically for the x86 architecture)?
So - what's going on?
Thanks so much!
Each year my company has its engineers do 20 to 30 hours of training. Since we use ARM cortex m4s on most of our products I thought it'd be good to get the ARM Accreditation. But for some reason ARM doesn't offer it anymore. Does anyone have any suggestions for some type of similar training course?
Is it truly as bad as Intel ME?
Can it be neutered or disabled like ME, and if so are any devices sold with it in such a state?
Is it at just a high privilege level as Intel ME?
Does it have higher level independent network access like Intel ME?
I am preparing to make a small linux board for myself that uses arm processor. I would like to know that if there's some processors (preferably cortex-a) that have qfp instead of bga package so that it's considerably easier to solder by hand?
I'm looking at something like a AT91SAM9260 chip. Anything similar is welcomed :D
Googling this question leads to a lot of chromebooks with 8-12 hours of battery life at a cheap price range, and a few Windows/Qualcom Snapdragon laptops with 24 hours of battery life but much more expensive. I would love to see a linux or chromebook laptop with 24 hours of battery life at a reasonable price point but am perhaps not doing a good search.
Would any of you know of a really long lasting ARM-based laptop at a reasonable price point?
Recently I struck a deal with a friend for his double-shot macchiatobin, which I would like to transform into a desktop. He himself has been using it as a desktop, but the only graphics card he's managed to get working was an NVidia GT 710. Problem is, to my knowledge the GT 710 doesn't have Vulkan support, and (more to the point) since I use Linux I'd be using the Nouveau drivers, which don't support Vulkan anyways. So my question is, has anyone has tried any graphics cards that they know to work with aarch64 and have Vulkan support?
If this isn't a possibility, I'll probably just go with the GT 710 since it's not that bad and is pretty cheap anyways.
Thanks in advance!
My wife (33F) is a SAHM with our son (4M) and we also have a daughter (6F) in school. Last Friday I get a frantic call from my wife around noon that our son fell off the top bunk while she wasn’t looking and now his arm looks really really swollen.
So I find him crying and holding an incredibly swollen, red arm sitting on the ground and refuses to let anyone touch it. My wife is sitting on the couch crying and saying how his arm looks so bad. I pick him up to go to the emergency room. I try to dress him since he can’t open his arms and ask her to get the car seat ready. She doesn’t move and keeps crying. I give up and do the best I can and call for my wife to get in...she just sobs and shakes her head saying “I can’t I can’t.” So I drive off without her.
I got really annoyed at my wife at this point. We get to the hospital and they want to run him through some X-rays and he’s screaming bloody murder. Around 3pm I get a call from my daughter’s school saying that no one’s picked her up... keep reading on reddit ➡
Actually I am working on NXP i.MX 8M Mini Evaluation Kit. The board has 4 x Cortex A53 Processors. It has a JTAG interface, but after researching online I found that most of the open source debugging softwares(openOCD) and low cost JTAG only support Cortex - M cores. Is it possible to setup JTAG and the debugging environment for cortex-A series of processors using these?
Hello, I have been trying to figure out how to replicate the strcpy function from C in arm assembly. What I have so far is:
strcpy: MOV R2, R1 @string trying to copy MOV R3, #0 @index strcpy_loop: LDRB R1, [R2, R3] CMP R1, #0 BEQ strcpy_end LDRB R0, [R2, R3] ADD R3, R3, #1 B strcpy_loop strcpy_end: BX LR
I am running into the issue of whatever the last char of the string I am trying to copy is, it is being saved in R0. For example if hello is the string I'm trying to cop, R0 will have o after the code is complete. I was thinking I would have to create an array of the chars I am attempting to load into R0 but I have no idea how to go about that. The function declaration looks like "void strcpy(char* a, char* b)".
Any input would be appreciated, as I am new to arm assembly!
I’ve been programming in Python on Linux. I’m new to ARM C++ programming. I’m starting with STM32 processors for learning. Please recommend an easy ARM C++ tool chain.
I tried Eclipse GCC GDB and I ran into lot of issues. I tried to solve them for two days and felt like I’m wasting lot of time on it.
Web/Video resources are appreciated. It’d be helpful all newbies.
I thought that ARM Cortex is a microarchitecture specification licensed by ARM Holdings, as is the ARM instruction set architecture.
For example, the Snapdragon 855 is an SoC (based on the ARMv8.2 architecture) with four Qualcomm Kryo 485 Silver cores along with three Kryo 485 Gold. The Kryo Gold/Silver 485 are respectively a Cortex-A76 and a Cortex-A55.
But in the case of the Samsung Exynos 9820 (based on the ARMv8.2 architecture too), it is an SoC with features 8 cores in a tri-cluster configuration consisting of two Mongoose 4, two Cortex-A75, and four Cortex-A55 cores. It is also confirmed by the official page.
What am I missing? Is ARM Cortex-* both a phys
The Hunter arms are muscled and armored in metal, but no shoulder pads (minimal shoulder pads can be cool too though) and no cloth sleeves. This is exactly how Titan arms should look. All Titan arms.
EDIT: The way people are commenting you'd think I actually have some kind of power over the direction Bungie takes with their armor visual design, which I don't. So would everyone please stop willfully interpreting this post in the most hyper-literal way possible in order to justify this freakout response of "no, not LITERALLY ALL ARMOR SHOULD BE EXACTLY LIKE THAT!" Like, yeah, no shit. I just would like to see a more sleek, less blocky, less trashbin design philosophy.
Warlocks are in a serious need for a class item that actually highlights their class. I barely notice my class item while on the inventory screen. If that happens there of all places, then who's going to notice it anywhere else?
What happened to the really cool bonds D1 had? They weren't perfect, yeah, and Titans and Hunters also suffered from the D2 transition, but neither as badly as Warlocks.
