Overo Airstorm mmc boot problem

Rate this Message:
Hello, I wonder if anyone can shed some light on the behaviour of a brand new
overo airstorm. When I plug in an micro sd card, it doesn't boot. On the serial console, I just see this: �tذb�$U @ @ @D�� However, if I unplug the micro sd card and power cycle, I see u-boot beginning, and if I interrupt u-boot, plug the card in, and enter 'run bootcmd' it boots linaro from the card. I'm a bit baffled as the problem seems to occur at a low level, before anything that can be configured. U-boot just doesn't seem to start when the card is plugged in. The card is a 2GB gumstix branded card. I have tried this with 2 different airstorms and a few sd cards, with the same results, so hardware failure is ruled out. I've also not had this problem with an earlier overo (tide). The output from u-boot (with no card) is as follows: Texas Instruments X-Loader 1.5.0 (Sep 16 2011 - 12:10:02) OMAP36XX/37XX-GP ES2.1 Board revision: 1 Loading u-boot.bin from nand U-Boot 2010.09 (Oct 20 2010 - 10:11:49) OMAP36XX/37XX-GP ES2.1, CPU-OPP2, L3-165MHz, Max CPU Clock 1 Ghz Gumstix Overo board + LPDDR/NAND I2C: ready DRAM: 512 MiB NAND: 512 MiB *** Warning - bad CRC or NAND, using default environment In: serial Out: serial Err: serial Board revision: 1 Tranceiver detected on mmc2 No EEPROM on expansion board Die ID #413800029ff8000001683b061202300b Net: No ethernet found.

I updated the MLO in flash as described here: http://gumstix.org/how-to/70-writing-images-to-flash.html with the latest version from http://cumulus.gumstix.org/images/angstrom/developer/current/MLO It didn't fix the problem. There is a slight change: if I insert an sd card which isn't bootable (i.e the one I used to save MLO), u-boot will now load and boot from nand. However, if I insert a bootable linaro card, the gumstix hangs as before, before even starting u-boot. Its as if u-boot doesn't like the sd card structure with the 2 partitions which is bootable. Any insights welcome..

I think you needed to update the MLO on the sdcard, not the one in nand.

apologies, I put the latest angstrom images on sd card and it does work.
this means that linaro isn't working on this gumstix (airstorm) at the moment. -- View this message in context: http://gumstix.8.n6.nabble.com/Overo-Airstorm-mmc-boot-problem-tp4539832p4542844.html Sent from the Gumstix mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ gumstix-users mailing list gumstix-users@... https://lists.sourceforge.net/lists/listinfo/gumstix-users |

The Linaro MLOs don't work with the STORM series COMs, but if you copy
MLO-updated and overwrite their MLO after you run linaro-media-create, it boots up. I don't know the details about how that works, but it does. If you don't trust it, you can always boot off nand using the MLO and u-boot on the nand, stop the autoboot, put the SD card in, and tell to boot. That way, you use a working MLO and u-boot (the one on the nand), and the Linaro kernel after you put the SD card in. How I understand it is the MLO boots first (the garbage when you first boot up), which starts up the u-boot (the nice text that tells you how much memory there is). -- View this message in context: http://gumstix.8.n6.nabble.com/Overo-Airstorm-mmc-boot-problem-tp4539832p4544168.html Sent from the Gumstix mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ gumstix-users mailing list gumstix-users@... https://lists.sourceforge.net/lists/listinfo/gumstix-users |

Thanks, that works.
I made a linaro bootable sd with the instructions from their site and then copied the latest MLO from cumulus.gumstix.org onto the card and it booted. -- View this message in context: http://gumstix.8.n6.nabble.com/Overo-Airstorm-mmc-boot-problem-tp4539832p4544941.html Sent from the Gumstix mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ gumstix-users mailing list gumstix-users@... https://lists.sourceforge.net/lists/listinfo/gumstix-users |
