Hi,

I have ConnectCore SBC 6ul pro board.
sysinfo shows:

|| MCA | HW_VERSION=1 FW_VERSION=0.12
|| I/O Expander | HW_VERSION= FW_VERSION=

It seems that IO expander firmware was not programed.
But on your web site: https://www.digi.com/resources/documentation/digidocs/embedded/dey/3.2/cc6ul/yocto_r_io-exp-firmware-update

Digi programs firmware inside this chip on the ConnectCore 6UL SBC Pro boards

I downloaded firmware file: 82004089_A.bin

Is this file the bootloader only? If no, where can I download bootloader for the IO expander? Do you have .elf file format available?

Thank you
David

If firmware is not initially programmed, then in needs to be programmed via JTAG:

or you can RMA the board and Digi will program it for you.

You need to uninstall any previous versions of microsoft365.com/setup including 2007, 2010, 2013, and/or 2016. If you do not uninstall previous versions of Microsoft Office and you install Office 365 your computer will not run any program of Office 365 properly.To access these free web apps, just head to and sign in with a free Microsoft account.

i think this is the only bootloader
