[Qemu-devel] [Bug 1082292] Re: [ARM] pflash_write: Unimplemented flash cmd sequence
The message from pflash_write is a warning which only says that the Intel flash emulation got a command sequence which is only supported by the AMD flash emulation. This warning is currently normal when Linux kernels try to determine the flash type. Linux tries AMD before Intel. So if there is any problem, it is not related to the flash emulation. The test scenario works without any problem on a Debian Linux host (tested up to the boot prompt). Note that there are three location where you get output: * stdout / stderr on the console * serial output from the emulation (Alt-Ctrl-3 in QEMU SDL window) * framebuffer output from the emulation (Alt-Ctrl-1 in QEMU SDL window) It takes some time until the kernel sends output to the framebuffer (therefore 50 % cpu load), but it works. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1082292 Title: [ARM] pflash_write: Unimplemented flash cmd sequence Status in QEMU: New Status in Linaro QEMU: New Bug description: I find the bug already reported on qemu-devel mailing-list [1] w/o replies also on other sources.
