Add QMTech Wukong Board

[SanadaShinken]

Hi, All

I had a FPGA board, the chip is Xilinx XC7A100T. The URL is https://github.com/ChinaQMTECH/QM_XC7A100T_WUKONG_BOARD. the board could be found in the following sites. https://www.aliexpress.com/item/4000170042795.html http://www.chinaqmtech.com/download_fpga

The below file is what I done until now. it could boot the fpga board, and run into bios. the qmtech_wukong.platform.txt is been put into platforms, and the qmtech_wukong.target.txt is been put into targets. the output terminal log is wukong.txt. if open the log file, there is a problem about ddr3 memory initialization. it is failed.

Could any one do me a favor to show me some hint to make the ddr3 memory initialization succeed?

If ddr3 memory initialization succeed, the next step is put linux image into flash, and run into linux world.

qmtech_wukong.target.txt qmtech_wukong.platform.txt wukong.txt

Thanks in advance

Thanks @SanadaShinken for the initial support. I will look at it very soon. For now I transfered the issue to LiteX-Boards.

Hi Sir:

Many Thanks LiteX Project, and You!!!!!

I'd made a workable version Linux + VexRiscV running on qmtech wukong board. But I still need your help to clearing some settings. I'll upload the setting file when I done some tests.

Hi @SanadaShinken,

great you manage to make it work yourself, that's the better way to learn :) (I was going to look at it). Feel free to create a PR with support for this board if it's working. Even if not perfect, I could review and clean it up.

Hi: You can try with my files over same board (I will load support maybe next year to official repository but more hands could be great). It's tested with Vexriscv linux, linux-smp up to 16 cores (first version without DMA and some additional configuration over image build), Ethernet (with some doubts about its max baudrate), spisdcard boot (with a pmod) and terminal over usb onboard. Now I'm working to activate HDMI in/out port and a 5Mpix cmos camera (litevideo is under study) but first I will test new repository version first.

Check it out and tell us your feedback @enjoy-digital take a quick look at it. I hope this helps.

BR. Carlos.

Hello @enjoy-digital :

Thank you very much. the setting board setting files are in the work.zip file. this setting files could boot up with https://github.com/litex-hub/linux-on-litex-vexriscv/files/5281217/kc705_2020_09_25.zip, but will fail with 2020-1215 prebuilt bit-stream after I update litex related repositories.

Hi, @Chgavilana :

Very thanks for your sharing. I did some tests based on your spi sd card setting, but still failed. the linux kernel will crash after spi sd card initialized. Could you do me some favor to give me some hint about how to debug this error?

below is my environments:

1. Vivado : 2020.1
2. Litex : update to 2020-1218
3. Linux-on-litex-vexriscv : update to 2020-1218

Hi @SanadaShinken Well, for me works fine, and with last version, kernel recognize sd card and mount over /dev directory. I recommend first check your hardware connection (I don't know what pmod you use, mine is a little rustic but with all signal with pull-up and 3.3V power from connector), next, copy files again over SD (and check your sd memory), and finally, check your make.py file adding Qmtech board (short way to generate all).

class Qmtech(Board):
#    SPIFLASH_PAGE_SIZE    = 256
#    SPIFLASH_SECTOR_SIZE  = 64*kB
#    SPIFLASH_DUMMY_CYCLES = 11
    def __init__(self):
        from litex_boards.targets import QMTECH
        Board.__init__(self, QMTECH.BaseSoC, soc_capabilities={
            # Communication
            "serial",
            "ethernet",
            # Storage
#            "spiflash",
#            "sdcard",
            "spisdcard",
            # GPIOs
            "leds",
            # Video
#            "framebuffer",
            # Monitoring
            #"xadc",
        }, bitstream_ext=".bit")

Send a screen of your error and I can check what other problem could be. Carlos.

Hello, @Chgavilana :

Thank you very much. the attachment file is what i use for wukong board. work.zip

the following message is the fail log after linux kernel boot up.

Hi All:

Many Thanks for Greate Litex Project!!! @enjoy-digital , @Chgavilana, many thanks!!

After update all related projects, the final gateware could bring up linux OS successfully!

the following devices is ok for the attachment setting files. backup.zip

DDR3
SPI SD Card
ethernet
serial

the boot log file is setting vexriscv CPU running at 100MHz and 150MHz. bootup_ok.txt bootup_ok_150MHz.txt

If @enjoy-digital want to add to litex, it is very ok to me. this issues could be closed.

Best Regards, BR, Sanada

Hi @SanadaShinken,

thanks for the feedback. I can add the board support to LiteX-Boards ye, if you don't want to create a PR yourself can you provide me a name and email I can use for the copyright?

@SanadaShinken: This has been integrated. I also did some review/cleanup on the Platform file in https://github.com/litex-hub/litex-boards/commit/b67b18caad1d3f352b30de0aaf2b28b6df54dd71.
