Re: [coreboot] Coreboot FILO payload build fails when USB support enabled

you can try to get filo to work, or you can work at John Lewis excellent work on JELTKA and see if you would be better off using a linux kernel instead. My bias is towards JELTKA, personally. ron

Re: [coreboot] Coreboot FILO payload build fails when USB support enabled

Hello Vipin, > Can you please suggest a solution and let me know why CONFIG_USB is removed > from my .config The prefix for libpayload's configurations options changed to CONFIG_LP_, lately. The last commit for FILO (60d45fc) tried to fix it, but seems to have missed some options. So CONFIG_USB is CONFIG_LP_USB, now. Also, if you get current FILO to compile with USB support, depending on your platform, it might not work as expected. I hit some strange regressions with older hardware this week, that I'm still investigating. Nico

Re: [coreboot] Coreboot FILO payload build fails when USB support enabled

Hi Experts, The trick for changing from CONFIG_USB to CONFIG_USB_DISK did help to compile but it doesn't seem to be correct fix and not helping at run time. I have configured libpayload with CONFIG_USB support but that define is not included in the filo/build/config.h. As a result I get debug message No USB stack in libpayload. So FILO is assuming that libpayload is not configured with USB stack. Here is a summary of problem and looking for your guidance 1. in Filo there are two configuration files (.config and lib.config) 2. When USB stack is enabled in libpayload CONFIG_USB=y is defined in lib.config but not in .config 3. build/config.h does not have CONFIG_USB defined. As a result all the code kept under CONFIG_USB macro in FILO source tree assumes that libpayload does not have USB stack. Can someone please let me know what is the correct procedure to include USB stack in libpayload and inform to FILO that yes libpayload really has usb stack support?

Actaully there is a debug("ok"); statement just after your last print. If you remove this things will be fine. For some reason just after relocation that debug print crashes.

Hi Peter, Wait a minute. I may be wrong in using xgcc as I am building manually (due to bug in my earlier thread http://www.coreboot.org/pipermail/coreboot/2014-October/078735.html) instead of using coreboot build environment which contains gcc. Let me try to build it with coreboot environment and I will confirm again. Thanks for your advice.

Hi Peter, FILO is built with xgcc. Infect if make crossgcc is not done before running make, FILO refuses to build. =============== Check if FILO is built using the reference xgcc toolchain created by 'make crossgcc' and not the toolchain installed by your distribution. It is probably easiest to ensure use of xgcc if you build FILO manually. //Peter ------------------------------ On Sun, Oct 12, 2014 at 3:24 PM, Vipin Gahlaut <gailu96(a)gmail.com> wrote: > Hi, > > If I enable debug_all option in configuration latest coreboot with filo > hangs like below > > FILO version 0.6.0 (vgahlaut@ubuntu) Sun Oct 12 02:47:44 PDT 2014 > boot EAX = 0x0 > boot EBX = 0x0 > boot arg = 0x0 > Current location: 0x101000-0x257fb7 > Relocating to 0x7e77000-0x7fcdfb7... > > Never proceed from here. > > >
