This series lets me build and run an initramfs with the published toolchain, after adding the patch 'unicore32: Add ocd console and qemu-defconfig to support qemu simulator' as well to get console output. So feel free to add
Tested-by: Guenter Roeck <linux@roeck-us.net>
to the series.
I have a couple of questions:
- After adding the patch 'unicore32: Add ocd console and qemu-defconfig to support qemu simulator', I only get console output, but no input. Is there a way (for example with a qemu command line option) to get input as well ? - Is it possible to connect a console to a serial device in qemu (in other words to run the image in qemu without the ocd console patch) ? - Is there a working description on how to create a toolchain for the _new_ ABI ? Alternatively, would it be possible to publish such a toolchain ?
Thanks a lot,
Guenter
