Subject: [Buildroot] Xtensa qemu nommu defconfig not working
Date: Fri, 25 Nov 2022 19:11:55 +0100	[thread overview]
Message-ID: <20221125191155.111c4ddc@windsurf> (raw)

Hello,

The configs/qemu_xtensa_lx60_nommu_defconfig builds correctly, but
fails to boot under Qemu:

[    1.158675] Freeing unused kernel image (initmem) memory: 460K

There were some changes in elf2flt:

9dd179d43ffe9be98035f921a0db2bf051b632fb package/elf2flt: fix fatal error regression on m68k, xtensa, riscv64
95402089c314fbc03b934f5fcf9c29db043d758c package/elf2flt: remove broken patch

9db5eb258cf492567bac33a33cb606f14045639d package/elf2flt: Remove Config.in.host

6d49446ebdbd32c1b4591c0aa8cacb189a69e318 package/elf2flt: add RISC-V 64-bits support

However, in commit 9dd179d43ffe9be98035f921a0db2bf051b632fb, Niklas
said about the qemu_xtensa_lx60_nommu_defconfig configuration: "xtensa
crashes when loading init, the same behavior as when reverting the bad
upstream elf2flt commit completely."

Max, do you think you could have a look at what is happening?

Best regards,

Thomas
