Hi, We are trying to boot Beaglebone Black without an SD card. ie irrespective of whether SD card is connected or not BBB should boot from eMMC alone. Our linux version is 3.2 and u-boot version is 2013.01.01.
We are testing different u-boot scripts to boot completely from eMMC. We were successful in the u-boot part. But for some reason linux keeps getting stuck during boot when SD card is not inserted. When SD card is inserted it continues booting. This is the place where it gets stuck: ================= 1.873260] mmcblk0: mmc1:0001 MMC02G 1.78 GiB [ 1.878112] mmcblk0boot0: mmc1:0001 MMC02G partition 1 1.00 MiB [ 1.884368] mmcblk0boot1: mmc1:0001 MMC02G partition 2 1.00 MiB [ 1.892486] mmcblk0: p1 p2 [ 1.897338] mmcblk0boot1: unknown partition table [ 1.903869] mmcblk0boot0: unknown partition table ================= If I am correct, mmcblk0 is the SD card. It seems somewhere in the kernel a routine is waiting for the SD card to be connected. Can this be disabled? We still need the SD card to be accessible from BBB, but the boot process should be completely independant of the presence or absence of SD card. We are tied to linux and u-boot versions for the time being and we would like to explore all our options before trying higher versions. Please advice.
