Issue with sd boot

Hi all. First, sorry my bad english. I am having a problem that is killing me. I flashed ARM debian on a SD (4gb) and always I must to press USR button to boot from SD card. Yes, ALWAYS! I don’t know if it is a firmware problem, SD problem or a power problem. This BBB is the second I have on production. The first works OK; once I boot from SD, it boots always. The first BBB I flashed debian-7.4-console-armhf-2014-04-18.tar image; the second debian-7.6-console-armhf-2014-08-13.tar image. Both downloaded from the link that http://elinux.org/BeagleBoardDebian provides.

No matter if I power up the BBB with USB on my laptop or DC Power Supply (2.5A), or both. Always the FIRST TIME I POWER UP I must to press USR button for boot from SD. Then BBB: turns on D2, D3, D4 user leds, D5 keep turned off, led ethernet port blink softly, and nothing more happens. On display (4DCAPE43-T) on black screen without showing Tux splashscreen and everything else… If If I disconnect USB or DC Power supply, and reset, BBB boots from SD (by RESETs, POWERs BUTTONS on board, or by commands on console). BUT If I remove totally current from BBB and reconnect any, then I must to press USR button.

The idea is not flash EEPROM with the seem image from SD, because I think it works like a life guard. Also I’m scared that bricks the BBB.

I am exhaust. No have concrete idea what it must to be. Any more, answer me plsssssss. Thanxx in advance.-

I guess you failed to notice this note in the directions:

"Black: NOTE: You'll need to hold the BOOT button on powerup..."

From the fat partition just rename "bbb-uEnv.txt" to "uEnv.txt" and
it''l boot just fine..

btw, the image i posted (12 hours ago 2014-10-29) has better support
for the 4dcape43-t

Just open /boot/uEnv.txt

and add:

dtb=am335x-boneblack-4dcape-43t.dtb
