Notes

EmuDiag.exe (available via the I-jet menu) should be used to update the firmware.
The newer firmware version for a particular probe is on the top.
Firmware updates are not related to any particular CPU or board support.
Release date is the date of the firmware release build, not the date of availability.

I-jet firmware versions

Directory: <install directory>\<target>\bin\jet\firmware\i-jet\v8.2
Date: 2020/11/04
  1. Added generic UART send and receive capability over a choice of pins on MIPI20/MIPI10 connectors.
  2. Currently, the UART is used mainly for SFI (Secure Flash Interface) protocol available 
	 on some newer STM32H7 Arm MCUs.
  3. Future versions of Embedded Workbench may provide integrated UART terminal capability.
    
Directory: <install directory>\<target>\bin\jet\firmware\i-jet\v7.2
Date: 2017/04/05
  1. Supports extra 256KB buffer (for more robust high-speed SWO) added in I-jet vB probes.
  2. Extra SWO buffer will be utilized by any IAR Embedded Workbench for Arm version.
  3. This firmware version is fully compatible with I-jet vA, but will bring no benefits.

Only available in IAR Embedded Workbench for Arm:

Directory: <install directory>\<target>\bin\jet\firmware\i-jet\v6.2
Date: 2016/04/29
  1. Support for cJTAG added (requires IAR Embedded Workbench for Arm versions 7.60.1 or newer).
  2. Enlarged SWO buffer to improve SWO with slow USB ports or USB power saving modes.
