You should be able to replace the kickstart and S1L without any problems, but they shouldn’t have any impact on whatever OS you are running on the board. It really looks like your just using older versions of the code, u-boot-1.3.3 is very old. Use u-boot-2009.03 instead. Verify you are using the 4.12. EABI toolchain. All this should be selected by default on a fresh build with unchanged LTIB configs. You might also want to clean out your rpm/BUILD area before you start a clean build, backing up any changes to the code you made. Kevin From: Krzysztof Stankiewicz [mailto:address@hidden Im using the clean build from CVS of uBoot, Kernel2.6.34 and rootfs generated by ltib. From: address@hidden I’ve just did a clean test build of the kernel and rootfs from the current LTIB patches. The configuration has only been modified to add mp3play, madplayer, and mplayer. On kernel boot, I see my ALSA device. This appears to be correct in your boot log too.

If you’ve made changes to the configuration, restore the original configuration and rebuild. I noticed some of the dates in your root filesystem are in November 2010. Let LTIB build the complete root filesystem from scratch and try that one just in case something is causing problems. I also noticed your using GCC 4.3.2. Don’t use this version. Use the default version that LTIB picks for you (4.1.2 EABI w/ VFP). GCC 4.3.2 is no longer an option for the LPC32xx boards and hasn’t been a selectable option for a while. Make sure your LTIB is up to date, use the cvs version, not the snapshot. Kevin Subject: RE: [Ltib] mp3play produces sound but mplayer doesnt? Hi Kevin, From: address@hidden I’ll try it when I get back to the office next week. PCMCIA shouldn’t be enabled in the kernel for the LPC32xx. Verify you have all the latest LTIB updates to get all the latest 32xx patches. Also build with the default kernel config just to make sure nothing has been changed in the kernel that can cause some type of problem. As of last check (a few months ago), mp3play, madplayer, and mplayer all worked fine. Kevin Subject: Re: [Ltib] mp3play produces sound but mplayer doesnt?
From: address@hidden Hi, It might require ALSA device nodes in /dev/snd/. Have you checked the setup for ALSA (check http://www.lpclinux.com/Forums/ForumLPC32xx0001) and also verified the volume is on? thanks, Kevin Subject: Re: [Ltib] mp3play produces sound but mplayer doesnt? Oh hi I meant;
