Hi ,

 

I was able to run QEMU with LS1043ardb on a debian VM running on my windows machine . I am using the SDK 2.0 and i have followed the steps in the document (https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf?fsrch=1&sr=3&pageNum=1 ) and have been able to complete the fsl-image-virt and was able to launch the qemu using the below command. I have built the base SDK without any additional changes.

 

./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-aarch64 -m 512 -mem-path /var/lib/hugetlbfs/pagesize-2MB -nographic -cpu cortex-a53 -machine type=virt -kernel ./tmp/deploy/images/ls1043ardb/Image -serial tcp::4446,server,telnet -initrd /home/sarayu/code/yocto_NXP_nocache/QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb/tmp/deploy/images/ls1043ardb/fsl-image-virt-ls1043ardb-20180405053052.rootfs.ext2.gz -append 'root=/dev/ram0 rw console=ttyAMA0 rootwait earlyprintk' -monitor stdio

 

Though i am able to launch qemu it shows the below error logs ,

 

[   13.084109] RAMDISK: gzip image found at block 0

So , when i try to create any file/folder i get the below error ,

root@ls1043ardb:~# mkdir temp
[ 4695.299191] EXT2-fs (ram0): error: read_block_bitmap: Cannot read block bitmap - block_group = 37, block_bitmap = 303105
mkdir: cannot create directory 'temp': Input/output error
root@ls1043ardb:~#

 

I am unable to do anything with the qemu because of this filesystem error.

Can you please help me resolve this issue ?

 

Thanks and Regards,

Sarayu
