TM4C123G ROM Bootloader and USB connection

Keith Smith

It discussed both the ROM and Flash boot loaders. What wasn't answered was what are the hardware requirements for the USB connection for the ROM

bootloader. i.e. Can the USB be used with the ROM bootloader and which pins need to be used for the USB DM/DP/VBUS, etc.?

Where would I find this information?

Hello Keith

Only DP and DM are required when using the ROM based boot loader.

Amit - Thank you for the information.

Does the ROM boot loader support BOOTCFG?

Hello Keith,

Sorry for the delayed response. Yes, it supports BOOTCFG. However do check the latest errata as there is a known issue.
