SemiDrive E36xx
Contents
The SemiDrive E36xx are Cortex-R5 based MCUs. They are composed of two CPU clusters with 5 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 |
---|---|
E3640 | Cluster 0 (CPU0) |
E3640_CPU1 | Cluster 1 Core 0 |
E3640_CPU2 | Cluster 1 Core 1 |
E3640_CPU3 | Cluster 2 Core 0 |
E3640_CPU4 | Cluster 2 Core 1 |
E3648 | Cluster 0 (CPU0) |
E3648_CPU1 | Cluster 1 Core 0 |
E3648_CPU2 | Cluster 1 Core 1 |
E3648_CPU3 | Cluster 2 Core 0 |
E3648_CPU4 | Cluster 2 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
E36xx devices have ECC RAM which can be disabled. However, a connect to CPU 0 of E36xx devices will initialize 1MB at 0x400000.
Reset
No device specific reset is necessary. The normal Cortex-R reset is performed.
