After booting of kernel, can I locate dhrystone stored in the SD card in arianne? #47

Could you tell me how to mount the second partition of the SD Card? Thanks!

I think you should be able to just mount it using normal linux commands (i.e., mount)

mount /dev/mmcblk0p2 /mnt then you can see the second partition of the SD Card in /mnt By the way, it's said that performance_counter module has not fully implement the use mode on released ariane 4.2 (or before) , you may meet illegal instructions error when running dhrystone or other benchmarks.

I tried this command yesterday, but there is an error

mount /dev/mmcblk0p2 /mnt

mount: mounting /dev/mmcblk0p2 on /mnt failed: Invalid argument

To properly part the SD card on the host PC: sudo fdisk -l # search for the corresponding disk label (e.g. /dev/sdc) sudo sgdisk --clear --new=1:2048:67583 --new=2 --typecode=1:3000 --typecode=2:8300 /dev/sdc -g # create a new //gpt partition table and two partitions: 1st partition: 32mb (ONIE boot), second partition: rest (Linux root) sudo mkfs -t ext3 /dev/sdc1 #make filesystem ext3 sudo mkfs -t ext3 /dev/sdc2 sudo dd if=bbl.bin of=/dev/sdc1 status=progress oflag=sync bs=1M#put Linux image bbl file on sdc1 sudo mount /dev/sdc2 /mnt #mount sdc2 to/mnt and copy your files to sdc2 , do not use dd sudo cp YourFiles /mnt then you can mount the second part of the sd card on ariane-sdk linux.

Thank you very much! The problem is solved!
