boot Ubuntu using PXE from U-Boot on the Samsung XE303C12-A01US Chromebook

by Mario

Hello. I'm trying to boot Ubuntu using PXE from U-Boot on the Samsung XE303C12-A01US Chromebook. I would like to understand better the point 5 of the tutorial here : https://wiki.linaro.org/Boards/Arndale/Setup/PXEBoot it says : "At the u-boot prompt, set the environmental variables "serverip" and "ipaddr" as per the board and host PC configuration. Now set the following environmental variables as mentioned..." the problem is that the Samsung XE303C12-A01US does not have a serial port and I can't stop the u-boot booting and set the enviromental variables manually. I would like to know how can I embed them inside u-boot. Also because there is not a configuration file like boot.cmd/boot.scr like there is on the pandaboard that can be used to pass the parameters. Thanks. -- Mario.

lists.linaro.org maintenance completed

by IT Services

This is to let you know that the migration of lists.linaro.org has been successfully completed. As per the email I sent on Wednesday, it may take some time for the new address of the server to be seen by your computer. You can check this by trying to connect to the web site: http://lists.linaro.org/ If you are able to connect and you do not get an error, this means you are connecting to the new server and you can send email to the lists. If you experience any problems after the weekend and you find that you still cannot connect to the server, please reply to this email to let us know. Regards Philip IT Services Manager Linaro

OMAP4 PandaBoard 4430 vs PandaBoardES 4460

by Péter Ujfalusi

Hi, First of all I'm not sure if this is the right list to post this, but I thought boot-architecture might be the best list to post. Currently we have one hwpack for PandaBoard4430 and PandaBoardES 4460 which means that when we install the hwpack on PandaBoardES the kernel thinks it is running on PandaBoard 4430. However there is a HW difference between the two boards: Audio routing is different (for capture path). Also the hdmi pin muxing need to be different (according to the DTS files). I can see two ways of dealing with the different versions: 1. create separate hwpacks for the revisions where only the included DTB file is different: PandaBoard 4430: omap4-panda.dtb PandaBoardES: omap4-panda-es.dtb 2. Or to have single hwpack for Panda: With the included patch in u-boot Include both omap4-panda.dtb and omap4-panda-es.dtb files to the boot partition. Modify the boot.txt to load different dtb based on the board: if is_pandaES; then setenv bootcmd "fatload mmc 0:1 0x80200000 uImage; fatload mmc 0:1 0x81600000 uInitrd; fatload mmc 0:1 0x815f0000 omap4-panda-es.dtb; bootm 0x80200000 0x81600000 0x815f0000"; else setenv bootcmd "fatload mmc 0:1 0x80200000 uImage; fatload mmc 0:1 0x81600000 uInitrd; fatload mmc 0:1 0x815f0000 omap4-panda.dtb; bootm 0x80200000 0x81600000 0x815f0000"; fi; For audio we need to tell the difference between the two revision and this is done via different DTB blob. Thank you, Péter

Planned maintenance - lists.linaro.org

by IT Services

Hello You are receiving this email because you are subscribed to one or more mailing lists provided by the lists.linaro.org server. IT Services are announcing planned maintenance for this server scheduled for *Friday 15th March 2013, starting at 2pm GMT*. The purpose of the work is to move the service to another server. There will be some disruption during this maintenance. In order to ensure that you do not accidentally try to use the service while it is being moved, the current server will be shut down at 2pm. A further email will be sent on Friday afternoon to confirm that the migration of the service is completed. However, due to the way servers are found, it may take a while before your computer is able to connect to the relocated service. After the old server has been shut down, email sent to any of the lists will be queued, but it is possible that the sending server will still trying to deliver the email to the old server rather than the new one when it is started. It is therefore *strongly* recommended that you do not send any email to an @lists.linaro.org email address until you can connect to the new service, which you will be able to test by trying to use a web browser to connect to http://lists.linaro.org after you receive the email confirming that the migration has been completed. Since the old service will be shut down, if you are able to connect, you can be sure you have connected to the new service. If by Monday you are still unable to connect to the service or you are not able to send email to an @lists.linaro.org email address, please send an email to its(a)linaro.org. Thank you. Regards Philip IT Services Manager Linaro
