Processor & Design Information
The Kintex Ult FPGA (KU19P) SOM is based on Xilinx Kintex Ult FPGA (KU19P) integrated with LS1021A
Layerscape Processor. Featuring a pair of extremely power-efficient 32-bit Arm Cortex-A7 cores with ECC protected L1 and L2
cache memories for high reliability, running up to 1.2 GHz, and providing pre-silicon CoreMark performance of over 5,000, the
LS102xA family delivers greater performance than any previous sub-4W communication processor. The Block Diagram of LS1021A
from NXP website is shown below for reference.

LS1021A Booting and Configuration
The Kintex Ult SOM integrates KU19P FPGA SoC with L1021A Layerscape processor. The RCW and U-boot is programmed
in to the NOR Flash. On POR, Pre-Boot Loader (PBL) will fetch RCW configuration and PBL commands from NOR flash (chosen by
rcw_src selection pins). Then executes u-boot from NOR flash.
