How to use 10Gbit ethernet on STKLS1046 with BSP REV.0003
In order to use the two 10 Gbit ethernet interfaces on the STKLS1046, the U-Boot bootloader has to be rebuilt with a new RCW configuration.
By default RCW 3333 (SerDes1) and 5559 (SerDes2) are configured in the TQMLS1046 U-Boot. This RCW configuration does not support 10Gbit ethernet.
In one of the next updates a U-Boot binary with a proper configuration for 10Gbit ethernet will be build by default.
RCW Configuration 1133_5559
As an example the RCW configuration 1133(SerDes1) and 5559(SerDes2) has been chosen for this how to.
See the tables below for further information about the RCW configuration.

| Lane D | Lane C | Lane B | Lane A | PCIe GEN1/2 PLL Mapping | PCIe GEN3 PLL Mapping |
| XFI.9 | XFI.10 | SGMII.5 | SGMII.6 | 2211 | N/A |

Rebuild U-Boot with RCW configuration 1133_5559
- After building the Yocto Image, following line has to be added to configuration file local.conf
UBOOT_RCW_CONFIG = "TQMLS1046A_RCW_1133_5559"
- Create a new Image with the following command:
bitbake core-image-minimal
STKLS1046 DIP Switch Configuration
According to the RCW 1133_5559 the DIP switches on STKLS1046 DIP must be set as follows:
