+The SiFive U54 Standard Core is a single-core instantiation of the world’s first RISC-V application processor, capable of supporting full-featured operating systems such as Linux.
+
+The U54 is ideal for low-cost Linux applications such as IoT nodes and gateways, point-of-sale, and networking.
+
+This target features:
+
+- 1 RV64GC U54 Application Core
+- 16KB L1 I-cache with ECC
+- 16KB L1 D-cache with ECC
+- 8 Region Physical Memory Protection
+- 48 Local Interrupts per core
+- Sv39 Virtual Memory support with 38 Physical Address bits
+- Integrated 128KB L2 Cache with ECC
+- Real-time capabilities
+- CLINT for multi-core timer and software interrupts
+- PLIC with support for up to 128 interrupts with 7 priority levels
+- Debug with instruction trace

+The SiFive U54-MC Standard Core is the world’s first RISC-V application processor, capable of supporting full-featured operating systems such as Linux.
+
+The U54-MC has 4x 64-bit U5 cores and 1x 64-bit S5 core—providing high performance with maximum efficiency. This core is an ideal choice for low-cost Linux applications such as IoT nodes and gateways, storage, and networking.
+
+This target features:
+
+- 4x RV64GC U54 Application Cores
+ - 32KB L1 I-cache with ECC
+ - 32KB L1 D-cache with ECC
+ - 8 Region Physical Memory Protection
+ - 48 Local Interrupts per core
+ - Sv39 Virtual Memory support with 38 Physical Address bits
+- 1x RV64IMAC S51 Monitor Core
+ - 16KB L1 I-Cache with ECC
+ - 8KB DTIM with ECC
+ - 8 Region Physical Memory Protection
+ - 48 Local Interrupts
+- Fully Coherent TileLink Bus
+- Integrated 2MB L2 Cache with ECC
+- Real-time capabilities
+- CLINT for multi-core timer and software interrupts
+- PLIC with support for up to 511 interrupts with 7 priority levels
+- Debug with instruction trace

+# SiFive HiFive Unleashed
+
+The SiFive HiFive Unleashed features an FU540-C000 SoC with the U54-MC Core IP.
+
+## Configuring MSEL
+
+The mode select switches should be set as follows:
+```
+ USB LED Mode Select Ethernet
+ +===|___|==****==+-+-+-+-+-+-+=================|******|===+
+ | | | | |X|X|X| | | |
+ | | | | | | | | | | |
+ | HFXSEL->|X|X|X| | | | |______| |
+ | +-+-+-+-+-+-+ |
+ | RTCSEL-----/ 0 1 2 3 <--MSEL |
+ | |
+```
+
+This will cause the board to boot from the SPI flash at 0x2000\_0000.
