Re: No output for lm3s6965-ek:qemu-protected
Hi Robin, Did you test previous release versions? It could be useful to know in which version the issue was introduced. After that we could use git bisect to pinpoint the commit that introduced this issues.

Re: No output for lm3s6965-ek:qemu-protected
Hi Alan. Thanks for the response. I forgot to add that I had tried to bisect things but I didn't get very far. This could be down to something silly at my end but either I couldn't get a successful build or I would hit the same situation as previously indicated. I decided to poke a bit further and have some points to share in the hope that they help: I went back to the first commit where support for this board was added like so: $ cd nuttx $ git whatchanged --pretty=oneline boards/arm/tiva/lm3s6965-ek/ configs/qemu-protected/defconfig | tail -n 2 702bc95cac16fe90cfaf8abb178b0822ba707521 tiva/lm3s6965-ek: Add a few configs for qemu $ git checkout -b test 702bc95cac16fe90cfaf8abb178b0822ba707521 $ ./tools/configure.sh lm3s6965-ek:qemu-protected $ make -j(nproc) .. which ended with: === AR (create): libboard.a lm_boot.o lm_leds.o lm_ethernet.o lm_ssi.o lm_appinit.o lm_bringup.o make[2]: Leaving directory 'nuttx_workspace/nuttx/boards/ arm/tiva/lm3s6965-ek/src' LD: nuttx arm-none-eabi-ld: Error: unable to disambiguate: -nostartfiles (did you mean --nostartfiles ?) make[1]: *** [Makefile:172: nuttx] Error 1 make[1]: Leaving directory 'nuttx_workspace/nuttx/arch/arm/src' make: *** [tools/Makefile.unix:412: nuttx] Error 2 === I 'fixed' that by omitting the offending ld switches manually.

Interestingly - and as indicated in my first post - a build with the latest nuttx and apps dirs doesn't produce the above output. However, when I look at my poor person's 'boot log' I see the same invocation of irq_unexpected_isr. My theory, therefore, is that lm3s6965-ek:qemu-protected has never worked ever since support was committed ? Also: I think the unexpected IRQ 11 (that's an SVC exception I think ?) has been the problem since the beginning and continues to manifest even with the latest nuttx. I would appreciate any advice. I will try and explore a bit further myself but I am very new to NuttX. Cheers, Robin On Mon, 13 May 2024 at 22:35, Alan C. Assis wrote: > Hi Robin, > > Did you test previous release versions?

Re: No output for lm3s6965-ek:qemu-protected
Thanks Alan! Would be great to get Yamamoto-San's views. Basically I want to showcase Nuttx as a good option for misc projects and the situation is such that I need the following attributes: 1. Cortex-M 2. Ethernet 3. Qemu Unless I'm mistaken, lm3s6965evb was the only board that met all 3 ? Cheers, Robin On Tue, 14 May 2024 at 18:48, Alan C.

Re: No output for lm3s6965-ek:qemu-protected
Exactly! Since you require Cortex-M, Ethernet and QEMU. I'm not sure if the qemu-system-arm package now has support for STM32, if it has it is possible to use some stm32 board. Another alternative could be RISC-V on QEMU, in case Cortex-M is not an essential requirement. Ah, and Xtensa (ESP32) also has support on QEMU, which is also an alternative (since it also supports Ethernet).
