Hi @SanadaShinken,
the prebuilt linux_2020_12_15 is only compatible with >= 2020_12_15 bitstreams. You will have to rebuild the bitstream for your board to use it.

Hi @enjoy-digital :+1:
Yes, I did the update to 2020-1218 for all of the litex related project. the file is the boot up message. the most interesting parts in the file is the following part.
wukong_boot_fail.txt [ 0.000000] Failed to find INTC node [/cpus/cpu@0] [ 0.000000] Failed to initialize '/cpus/cpu@0': -19 [ 0.000000] timer_probe: no matching timers found
wukong_boot_ok.txt is using kc705_2020_09_25.zip's Image and rootfs.cpio wukong_boot_ok.txt
in the workable Image and rootfs.cpio, there are some messages about litex-spiflash show that the device did not work properly.
[ 4.595471] litex-spiflash f0005800.spiflash: unrecognized JEDEC id bytes: ff, ff, ff [ 4.596087] litex-spiflash f0005800.spiflash: SPI_NOR_SCAN FAILED [ 4.596929] litex-spiflash: probe of f0005800.spiflash failed with error -2
BTW, the DDR3 memory R/W speed is very slow with compare to using the same DDR3 chip, such as like atry-7. is there any idea about improve memory access speed?
