When I build the kernel and follow the instructions for an SD Card boot using the development board the boot errors out with: [ 3.797424] mmc1: error -110 whilst initialising SD card .... snip .... [ 3.905212] Waiting for root device /dev/mmcbulk1p2... And never loads. I have tried multiple SD Cards and built the kernel both using the VM and natively following the Linux Mainstream BSP instructions. Is this a known issue? I have tried experimenting with different device names (mmcbulk0p2, mmc0p2, mmc1p2) and different format options (ext3, etc) in the boot args and I'm kind of at a loss. The ramfs version build and boot fine, but I need need to be able to store things between boots. Any clues, did I miss something in the BSP Guide?

It appears there is a spelling error on the device name. It should /dev/mmcblk1p2 (blk not bulk) adam

Adam, Sorry that's my fault, I had 'mmc0p2' in there from one of my prior runs and I "found and placed" it with that spelling error of 'mmcbulk1p2' instead of 'mmcblk1p2'. Just to be doubly positive I re-ran it and it had the same result: .... snip .... [ 3.797515] mmc1: error -110 whilst initialising SD card .... snip ....

Also u-boot's ext4ls so no problems listing the partition with the root file system on it and error: -110 is ETIMOUT, so I'm wondering if there is something that needs to be changed in the device driver?

James, I cannot replicate your issue, but there was some discussion a while ago in the Linux community about the gpio muxing. In the kernel, there is a file called: arch/arm/mach-omap2/pdata-quirks.c Look for a function that reads static void __init omap3_logicpd_torpedo_init(void) Could you could try commenting out the following line to see if it makes any difference after rebuilding the kernel? /* omap3_gpio126_127_129(); */ I'll post my boot log in the next message

Adam, No joy unforetunately on commenting out omap3_gpio126_127_129. I also so the compiler warning for omap3_gpio126_127_129 being declared but not used so I know it actually made it into the compilation. Boot still hangs waiting for /dev/mmcblk1p2. I recompiled the kernel with MMC device driver debug turned on and was able to get the torpedo to boot into Linux. Of course then I had to also see all the MMC operations while I'm issuing commands over serial. :-) The debug output looks like it is trying to enurate what kind of SD Card I have plugged in and then after roughly 20 seconds figures out what kind of SD Card it is and boots from it. This is just a guess based upon the other debug around what was going on, I didn't actually look up the message IDs. I also removed rootwait from the boot line to force it to tell me what partitions are available and I saw /dev/mmcblk1p2, so I know that it is in /dev. I read somewhere on a xilinx forum that there is a timeout somewhere in the MMC device driver that cause simliar behavior to this. So I'm going to see if I can whatever timeout is in there and extended. If you have any other guess, I'm all ears because this is really strange....I'm also starting to wonder if the development board is somehow damaged....but that wouldn't explain how the ramfs works just fine so its probably not that.

Have you tried different SD cards to see if you can narrow it down to a brand and/or speed rating? U-Boot may not be as aggressive to setting speeds, whereas Linux will try to push the speeds depending on the SD card info returned. If you eject the card and re-insert the card once it starts to wait, can you see if it works? It could be transitioning from one state to another and getting hung up in the transition state from whatever U-Boot configured to whatever Linux configured. Also, if you boot from a RAMdisk, are you able to mount the ext partition on the SD card and read/write to it? adam

LogicPD WinCE Demo 6.0 SD Card (I peeled the sticker off and the card has no markings and googling the numbers on the back don't tell me anything): Results in the waiting for /dev/mmcblk1p2 error. c. LogicPD Linux SD Card (same as above): Results in the waiting for /dev/mmcblk1p2 error. d. San Disk Micro SD HC 32 GB Class 2: Works just fine, booted on the first try. I pulled this card out of an old Gumstix Overo Fire which is also an OMAP3 architecture so I figured it might work. 2. Ejecting and re-inserting the cards from 1.b. and 1.c. does not appear to change anything it is still waiting at the /dev/mmcblk1p2 line. 3. Testing the ramdisk from 1.b. and 1.c.: 1.b. With the card split 50/50 FAT32 boot partition and EXT4 partition, the SD Card does not appear in /dev. 1.c. 1. Using the card in its factory provided state and a cleared nand chip the SD Card's boot partition is mounted at /mnt/mmcblk1p1 2. With the card reformatted to a 50/50 split FAT32 and EXT4, nand cleared and boot env set as per the RAMDisk section of the SDK user guide, it boots but the again the device is not visible from /dev. [Conclusion] It seems that the card speeds is the culprit and that I should stick to class 2 SD Cards or modify some stuff in Linux to make it work :-)

Ok so I found the answer for the Kernel panic with the SDXC card as per: AM/DM37x Multimedia Device TRM: 24.1.1 MMC/SD/SDIO Features The main features of the MMC/SD/SDIO host controller are: • Full compliance with MMC command/response sets as defined in the Multimedia Card System Specification, v4.2 including high-capacity (size > 2GB) cards HC MMC. • Full compliance with SD command/response sets as defined in the SD Memory Card Specifications, v2.0 including high-capacity SDHC cards up to 32GB. • Full compliance with SDIO command/response sets and interrupt/read-wait mode as defined in the SDIO Card Specification, Part E1, v2.00 • Full compliance with sets as defined in the SD Card Specification, Part A2, SD Host Controller Standard Specification, v2.00 And according to Wiki: The Secure Digital eXtended Capacity (SDXC) format, announced in January 2009 and defined in version 3.01 of the SD specification. So that explains that. So my bad I should have RTFM on this one.
