I had my BBB and I’ve been needing something to do i2C work with python or perl. Unfortunately, I was still on Debian 9 from years ago and couldn’t get the bits and bobs necessary. So I wanted to upgrade it to the latest Debian.<\/p>\n\n\n\n
I was able to snag a nice 32Gb microSD card from a coworker. And I downloaded the compressed image file with my work PC.<\/p>\n\n\n\n
But it was a bust when it came to writing the image to the SD card on Windows, I ran into the “you must be Administrator” screen which means an IT ticket and some waiting time.<\/p>\n\n\n\n
I have all of the permissions I need on the BBB. But there’s not enough space in the onboard “drive” memory to hold the compressed image.<\/p>\n\n\n\n
So I made two partitions on the SD card, each 6 Gb. And I marked them as FAT format (I think it was flavor #8).<\/p>\n\n\n\n
Then I took the card back to Windows and copied the compressed image to partition #2.<\/p>\n\n\n\n
Back on the BBB again, I ran the de-compression and a dd <\/strong>command to copy the uncompressed image to the whole-drive device of the SD card.<\/p>\n\n\n\n xzcat image-file | <\/em>dd of=sd-card-device <\/em> bs=1M<\/strong><\/p>\n\n\n\n My hope was that the process wouldn’t be looking at the disk partition info after the start.<\/p>\n\n\n\n It ran for awhile and then finished.<\/p>\n\n\n\n I rebooted and held the button down for it to boot from the SD card, which it did. And I had my Debian 12.<\/p>\n\n\n\n Not only that but the 2nd partition is still available on the SD card so it must not have clobbered the partition table in the process.

[No, I had that wrong. The SD card was completely reformatted. But the EMMC memory was untouched and I could mount that or reboot without the card to the old system.]<\/p>\n","protected":false},"excerpt":{"rendered":"
