Format SD card while on UEFI shell

Format SD card while on UEFI shell

[Shubham Mittal]

Hi all,


Is there any utility/tool by which i can format sd card(connected to board) using UEFI shell.

As of now, i have to detach it and format it and attach it again..



Thanks,

Shubham Mittal

I'm not sure this answers your question or not, but Intel has some UEFI
disk utilities, but they're pre-EDK2 and non-BSD licensed. So you can
fdisk/format from within the UEFI Shell, for FAT volumes. Brian of Intel
says that there is work underway to revise these tools, unclear of what
(perhaps relicense these tools, make them work with current toolchain,
and perhaps transfer them from Intel to UEFI Forum) and when. See this
message:

Hmm, it looks like URL has changed:
https://firmware.intel.com/content/uefidiskutilitiesagreement
And the zip is no longer password-protected, thanks Intel lawyers!
But the contents appear to be still last-updated in 2011.

The SD spec calls out MBR with a single partition and FAT32 or exFAT file system based on size.  You need to follow those rules if you want to use it with embedded devices. A general purpose OS will treat the SD card like a disk and the format does not really matter.

Thanks Blibbet for your suggestions, i am trying to go through the links you provided..

Thanks Andrew but i think i need to format the sd card as i am making an application which tests the block i/o devices and sd card when tested, gets corrupted.


Thanks,

Shubham

I implemented gpt partitioning tool capable to format partitions/devices
and submitted that to the UEFI community a while ago
(I am away from my PC until next Monday, so you need to search for it
(UefiShellGptCommandLib) if it is urgent for you).
With that one you format your SD card with
gpt fatformat YOUR_SD_SHELL_BLK_ALIAS from within the UEFI Shell.

Thank you,
Vladimir
