I have been trying to create a vxworks target on a raspberry pi 3b+ from this [guide] README_raspberrypi3b), but I can’t get into any of the files on the sd card. When I try to, it gives a “cd: error = 0x2.” which I think just means “not found”. When I run the devs command, sd0a doesn’t show up. Any ideas?
Thanks
