19 Errata
19.1 DVK hardware errata
19.1.1 Port E0 on EFM32 MCU board disconnected
Kit Revisions
Rev A
Description
Revision A kits are shipped with engineering samples of the EFM32. On MCU boards containing these
engineering samples, port E0 on the EFM32 is disconnected. The MCU boards in question are shipped
with a sticker indicating that port E0 is disconnected.
19.2 DVK firmware errata
19.2.1 VMCU regulator
Firmware Revisions
1.0.1
Description
Firmware version 1.0.1 contains an I2C driver that on some occasions hangs. When this happens, VMCU
freezes and can no longer be changed. The same issue may also result in wrong VMCU setting after
startup. A power cycle of the DVK fixes the problem. This errata is fixed in firmware version 1.1.1 or
newer.
19.2.2 Storing user configuration
Firmware Revisions
1.0.1
Description
Firmware version 1.0.1 contains an I2C driver that on some occasions hangs. When this happens, user
configuration may no longer be stored. A power cycle of the DVK fixes the problem. This errata is fixed
in firmware version 1.1.1 or newer.
19.2.3 Debug mode setting
Firmware Revisions
1.0.1
Description
When changing debug mode using the GUI, the actual configuration of the debug interface is not always
the same as the debug mode set by the GUI. An upgrade to firmware version 1.1.1 or newer fixes this
errata.
