So when I flash iotbox.img on my SD card with etcher, I see my SD card is divided into two different drives. One says boot the other one is just drive.
If I put the flashed SD card in rpi 4b 8gb, it boots without any problems and I can use pos as normal.
I can access the boot drive on my pc but when I try to access the other drive, it tells me I need to format first. If I just close without formatting, I can't access the drive at all. If I chose to format, I see empty drive and it no longer works on my pi anymore.
