Compiling and flashing
The LS1021A-TSN board comes along with a microSD card with OpenIL U-Boot that can be used to update its internal QSPI flash (which is empty out of the factory).
To compile and flash an SD card image:
make ls1021atsn_sdcard_defconfig && make -j 8 && sudo cp u-boot-with-spl-pbl.bin /srv/tftpboot/ => tftp 0x82000000 u-boot-with-spl-pbl.bin && mmc rescan && mmc erase 8 0x1100 && mmc write 0x82000000 8 0x1100
For the QSPI flash, first obtain the Reset Configuration Word binary for bootimg from the QSPI flash from the rcw project (https://source.codeaurora.org/external/qoriq/qoriq-components/rcw):
make -j 8 && sudo cp ls1021atsn/SSR_PNS_30/rcw_1200_qspiboot.bin.swapped /srv/tftpboot/
The above RCW binary takes care of swapping the QSPI AMBA memory, so that the U-Boot binary does not need to be swapped when flashing it.
To compile and flash a U-Boot image for QSPI:
make ls1021atsn_qspi_defconfig && make -j 8 && sudo cp u-boot.bin /srv/tftpboot/
Then optionally create a custom uboot-env.txt file (although the default environment already supports distro boot) and convert it to binary format:
mkenvimage -s 2M -o /srv/tftpboot/uboot-env.bin uboot-env.txt
To program the QSPI flash with the images:
=> tftp 0x82000000 rcw_1200_qspiboot.bin.swapped && sf probe && sf erase 0x0 +${filesize} && sf write 0x82000000 0x0 ${filesize} => tftp 0x82000000 u-boot.bin && sf probe && sf erase 0x100000 +${filesize} && sf write 0x82000000 0x100000 ${filesize} => tftp 0x82000000 uboot-env.bin && sf probe && sf erase 0x400000 +${filesize} && sf write 0x82000000 0x400000 ${filesize}
The boards contain an AT24 I2C EEPROM that is supposed to hold the MAC addresses of the Ethernet interfaces, however the EEPROM comes blank out of the factory, and the MAC addresses are printed on a label on the bottom of the boards.
To write the MAC addresses to the EEPROM, the following needs to be done once:
=> mac id => mac 0 00:1F:7B:xx:xx:xx => mac 1 00:1F:7B:xx:xx:xx => mac 2 00:1F:7B:xx:xx:xx => mac save
The switch ports do not have their own MAC address - they inherit it from the master enet2 port.
Known issues and limitations
- The 4 SJA1105 switch ports are not functional in U-Boot for now.
- Since the IFC pins are multiplexed with QSPI on LS1021A, currently there is no way to talk to the CPLD for e.g. running the "qixis_reset" command, or turning the fan on, etc.
