Why J-Link OB?
The J-Link on-board (J-Link OB) was designed in order to provide a low-cost, space-saving
and on-board alternative to the general J-Link, for eval board manufacturers. J-Link OB can
be used with the same software package as the general J-Links and can be used with the
same utilities (as far as the feature set of the J-Link OB supports this)
Note
It is not allowed to use J-Link-OB-STM32F072-128KB (Cortex-M) for stand-alone em-
ulators.
