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.
