BBB freeze at "reading u-boot.img"

I’m using a BBB Rev A5C. I’ve been successful developing programs using Cloud9 for several weeks, but the board has suddenly started to freeze while reading the u-boot image.
The first 13 or so debug messages look the same as a normal boot, but stop at “reading u-boot.img”. Looking at other entries in this group and across the web, I’m not seeing this specific kind of fault or resolution.

The only thing I’m unsure about is that, due to a previous project, I had one I/O pin grounded while the pin was not initialized properly. I don’t have the specific pin, but I think it was P8-pin18 based upon one of the Cloud9 switch-reading examples.

I have a 5V, 1A supply and I have tried several of the suggestions about powering up while holding the “power” button on. Always the same debug messages.

I have created a microSD with a BBB-eMMC-flasher image, but the resulting messages remain the same. It appears to me that the second stage bootloader is not functioning or the u-boot image is corrupted. Any ideas for troubleshooting or repair would be appreciated.

Remove all capes and connectors.

and try re-flashing with the latest snapshot:

I used compressed file:

[https://rcn-ee.net/rootfs/bb.org/testing/2014-12-31/lxde/BBB-eMMC-flasher-debian-7.7-lxde-armhf-2014-12-31-2gb.img.xz](https://rcn-ee.net/rootfs/bb.org/testing/2014-12-31/lxde/BBB-eMMC-flasher-debian-7.7-lxde-armhf-2014-12-31-2gb.img.xz)

uncompressed using sudo xz -d filename.xz on an ubuntu machine

Installed the microSD and unmounted it.

sudo dd bs=1M if= <image file> of=/dev/sdb

Checked for two partitions;  BEAGLEBONE and rootfs

The flash process on BBB yielded power light only and debug records:

U-Boot SPL 2015.01-rc4-00002-g76c2d3b (Dec 30 2014 - 20:48:45)
spl: mmc init failed: err - -19
### ERROR ### Please RESET the board ###

Humm, this was an issue a day before that image.. What happens when
you hold down the boot button, before you power the board. (you can
let off of the boot button when all 4led's are lit)

Regards,

The previously posted 3-line debug log is what results from holding the boot button (S2 near the microSD slot, right?) down during power-up. No LEDs except power.

U-Boot SPL 2015.01-rc4-00002-g76c2d3b (Dec 30 2014 - 20:48:45)
spl: mmc init failed: err - -19

ERROR ### Please RESET the board

If I just power up with the SD card in place, but not holding the boot button, the original 13 lines of debug plus “reading u-boot.img”, no LED action except power.

Okay hot off the press:

please test.
