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://github.com/nxp-qoriq/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.
