I tried with both core-image-minimal and core-image-base. I am using the meta-xilinx layer, virtex5.conf http://git.yoctoproject.org/cgit.cgi/meta-xilinx/plain/conf/machine/virtex5.conf has the following entry # Don't use tty1 # USE_VT = "0" SERIAL_CONSOLE ?= "115200 ttyUL0" # Device nodes add xsa for (system ace) IMAGE_DEVICE_TABLES = "files/device_table-minimal.txt \ files/device_table_add-xsa.txt" There is a device_table_add-xsa.txt file, whose contents are as follows: # Add nodes for xilinx system ace /dev/xsa b 640 0 0 125 0 0 0 - /dev/xsa1 b 640 0 1 125 0 0 0 - /dev/xsa2 b 640 0 2 125 0 0 0 - /dev/xsa3 b 640 0 3 125 0 0 0 - /dev/ttyUL c 666 0 0 204 187 0 1 4 Perhaps this is the reason? Should there be an additional entry for /dev/ttyUL0 ? How can I ensure that udev runs? Best regards, Elvis Dowson
