The SemiDrive E34xx are multicore Cortex-R5 based MCUs. They are composed of two CPU clusters with 3 cores in total. J-Link offers access to each core by using the specific device name. Supported E34xx devices are:

Device Name CPU Cluster & Core
E3420 CPU0
E3420_CPU1 CPU1 Core 0
E3420_CPU2 CPU1 Core 1
E3430 CPU0
E3430_CPU1 CPU1 Core 0
E3430_CPU2 CPU1 Core 1

Internal Flash

E34xx devices have no internal flash.

QSPI Flash

QSPI flashes are not supported by J-Link. Refer to the J-Link Device Support Kit for adding support by yourself.

ECC RAM

E34xx devices have ECC RAM which can be disabled. However, a connect to CPU 0 of E34xx devices will initialize 1MB at 0x400000.

Reset

No device specific reset is necessary. The normal Cortex-R reset is performed.
