[Qemu-devel] [Bug 1731588] Re: qemu-system-arm black screen and keyboard not detected

[Peter Maydell]

"stm32-p103" is not a board model supported by upstream QEMU. Presumably
you're using a fork of QEMU -- you should ask whoever is responsible for
that fork about it.


For the second command line -- is the binary you're trying to run built for the 
stellaris board model you're trying to run it on? If it's the same binary you 
tried to use with the stm32 board model then I wouldn't expect it to work. You 
need to build a binary that targets the board model you run with.

Title:
  qemu-system-arm black screen and keyboard not detected

Status in QEMU:
  New

Bug description:
  Hi guys,

  I try to emulate FreeRTOS with this guide : 
http://wiki.csie.ncku.edu.tw/embedded/Lab32
  But, the keys on my keyboard are not taken into account. 
   - Command line : qemu_stm32/arm-softmmu/qemu-system-arm -M stm32-p103 
-monitor stdio -kernel build/main.bin -semihosting
  If I try to add usb flag with : qemu_stm32/arm-softmmu/qemu-system-arm -M 
stm32-p103 -monitor stdio -kernel build/main.bin -usb -device 
usb-host,hostbus=1,hostaddr=1 -show-curso
  I obtain this message "qemu-system-arm: -device 
usb-host,hostbus=1,hostaddr=1: 'usb-host' is not a valid device model name"

  My second option is try with the latest version of qemu with this
  command line : "qemu-system-arm -M lm3s6965evb -monitor stdio -kernel
  build/main.bin -semihosting" but I obtain a black screen.

  Could someone guide me on this problem ?
