bare-metal

QtCreator has a plugin named "Bare Metal". Bare Metal means a computer without an operating system. I have not seen much about Qt Bare Metal development. Is it a way to develop Qt for a bare metal system? Does Qt run on a system with no OS? If yes, what are the advantages of this approach for embedded system development? Is it a way to develop Qt for a bare metal system? No. Does Qt run on a system with no OS? No. Bare Metal means you usually have a few KB of RAM and ROM. I think you are confusing Qt (framework) with QtCreator (IDE). Tim Sander explains it clearly here at the Qt Developer Days

I am currently working with Gem5 and I have to access via UART from my Host to ARMv8 bare-metal option, so i tried lots way but i stocked yet. could you please let me know, how can i map my host's Serial port to ARMv8's Serial Port in bare-metal type programming. Any help would be appreciated Working setups This repository contains a highly automated working example . Features: works on both QEMU and gem5 works on both arm and aarch64 newlib allows using the standard C library optionally semihosting exemplified works on both RealViewPBX and VExpress_GEM5_V1 . You should prefer VExpress_GEM5_V1

I am experienced in implementing critical sections on the AVR family of processors, where all you do is disable interrupts (with a memory barrier of course), do the critical operation, and then reenable interrupts: void my_critical_function() { cli(); //Disable interrupts // Mission critical code here sei(); //Enable interrupts } Now my question is this: Does this simple method apply to the ARM architecture of processor as well? I have heard things about the processor doing lookahead on the instructions, and other black magic, and was wondering primarily if these types of things could be

I am assembling a cross compiling unit testing rig for an ARM system and running the tests on a host machine with qemu-system-arm . Specifically, I'm using qemu to emulate the Stellaris LM3S6965 eval board as it contains a Cortex M3 processor like my target environment. The binary run in qemu is built with GNU Tools for ARM. There is no OS involved. The test suite is run as a bare metal application with qemu in -nographic mode. The toolchain and the test rig itself are working fine. And the tests successfully run to completion and produce test results within qemu just fine as well. The problem

I am trying to get this tutorial to work as intended without success (Something fails after the bl main instruction). According to the tutorial the command (qemu) xp /1dw 0xa0000018 should result in the print 33 (But i get 0x00 instead) a0000018: 33 This is the content of the registers after the main call (see startup.s) (qemu) info registers R00=a000001c R01=a000001c R02=00000006 R03=00000000 R04=00000000 R05=00000005 R06=00000006 R07=00000007 R08=00000008 R09=00000009 R10=00000000 R11=a3fffffc R12=00000000 R13=00000000 R14=0000003c R15=00000004 PSR=800001db N--- A und32 FPSCR: 00000000 I
