If you have issues with ESP32 not booting with SD card but booting without SD card then then the fuse burn script from ulx3s-bin should be run. So far so good, you erased its flash, try linux. If no issue then can try to flash micropython and my new ESP32 OTA programmer ecp5.py end uftpd.py I have wisely taken some esptool.py which works and frozen it in ulx3s, versions change all the time and maybe you took something in the middle of development action :) install micropythonhttps://github.com/emard/esp32ecp5/ dpavlin@nuc:/nuc/FPGA$ git clone https://github.com/emard/esp32ecp5/ dpavlin@nuc:/nuc/FPGA$ cd esp32ecp5/ dpavlin@x200:/mnt/nuc/FPGA/esp32ecp5$ wget https://micropython.org/resources/firmware/esp32-idf3-20191120-v1.11-580-g973f68780.bin It's important to erase flash or micropyhton will complain about corrupt fat filesystem like:

Welcome to MicroPython on the ESP32!
For generic online docs please visit http://docs.micropython.org/
For access to the hardware use the 'machine' module:
import machine
pin12 = machine.Pin(12, machine.Pin.OUT)
pin12.value(1)
pin13 = machine.Pin(13, machine.Pin.IN, machine.Pin.PULL_UP)
print(pin13.value())
i2c = machine.I2C(scl=machine.Pin(21), sda=machine.Pin(22))
i2c.scan()
i2c.writeto(addr, b'1234')
i2c.readfrom(addr, 4)
Basic WiFi configuration:
import network
sta_if = network.WLAN(network.STA_IF); sta_if.active(True)
sta_if.scan() # Scan for available access points
sta_if.connect("<AP_name>", "<password>") # Connect to an AP
sta_if.isconnected() # Check for successful connection
Control commands:
CTRL-A -- on a blank line, enter raw REPL mode
CTRL-B -- on a blank line, enter normal REPL mode
CTRL-C -- interrupt a running program
CTRL-D -- on a blank line, do a soft reset of the board
CTRL-E -- on a blank line, enter paste mode

So, I have now managed to build oberon with diamond 3.7.
1. Build it with diamond 3.11, which fails
Thanks @kost for adding for adding make and libxslt to the docker image. It would be useful if you could patch the platform_check to allow versions before 3.11 to run on 5.* linux. docker pull dok3r/diamond:v3.7
woohoo! Cool

I have i2c in SaxonSoc in other projects such as https://github.com/SpinalHDL/SaxonSoc/blob/dev/hardware/scala/saxon/board/blackice/BlackiceSocArduino.scala#L25 The generated board support packages include a generated dts, but it is not used yet and the simple i2c generator that I wrote does not generate the dts. There is a problem building SaxonSoc Linux, that some build randomly do not work. It seems to be something to do with SDRAM access. @Dolu1990 is about to redo the SDRAM access for the Ulx3s, which should make it more reliable and faster, as he plans to support double frequency access. There is a lot of information on the development of the u-boot version here , which might be useful to you - SpinalHDL/SaxonSoc#7 https://github.com/SpinalHDL/SaxonSoc/pull/7 I2c Linux support will also need a spinal.lib driver here - https://github.com/SpinalHDL/linux/tree/linux-5.0.y/drivers/i2c The terasic De1Soc version of SaxonSoc Linux has a dts entry for an led for disk access - https://github.com/SpinalHDL/buildroot/blob/saxon/board/spinal/saxon_default/spinal_saxon_default_de1_soc.dts#L194 We really need a better GPIO mapping for the Ulx3s. That might involve including adding a second gpio peripheral to the hardware (gpioB) and doing a better lpf file mapping to pins. It might mean increasing the niumbers of pins that support interrupts. It would be good to include access to the buttons and switches and to make it easy to add Pmods that need interrupt support like the enc28j60 one. u-boot config for 85f with 64M SDRAMModify bootcmd to include: load mmc 0:1 0x80000000 /boot/uImage load mmc 0:1 0x81EF0000 /boot/dtb fdt add 0x81EF0000 fdt memory 0x80000000 0x04000000 bootm 0x80000000 - 0x81EF0000 ppp networkingov7670 pmodhttps://github.com/goran-mahovlic/fpga-odysseus/tree/master/projects/OV7670-HDMI pmod pin mapping: https://github.com/goran-mahovlic/fpga-odysseus/blob/master/projects/OV7670-HDMI/ulx3s.lpf#L335 SCCB Pullup Resistorsfrom https://github.com/westonb/OV7670-Verilog The SCCB interface for the camera requires pull up resistors. You need to solder 4.7K resistors from the SIOD and SIOC pins on the camera to the 3.3V supply. You can do this yourself or have the staff in the EDS help you. csihttps://twitter.com/mad_archer_/status/1231249513509261313 https://github.com/libv/fosdem-video-linux litex(just links, need to test it)

I was trying out the ecp5pll from @emard. I get it running and the clock adjustment seems to work, but somehow it does not get shifted for me. Is this currently not working with yosys and so forth, is there anything I have to take care of, or might it just be a bug on my side? Tried to search this chat a bit and just searched a bit on the internet but the things I found about it were quite old and not necessarily about my problem. Any ideas? I am using the vhdl version btw emard There's some order of signals and small delays between them for dynamic shifting to work. https://github.com/emard/ulx3s-misc/blob/master/examples/sdram/memtest_mister/hdl/top/top_memtest.v#L73 here is module to control phase shifts by pressing of BTN for testing of SDRAM with variable phase shift of the clock to chip Mario Hoffmann alright, ill look at that. thanks Mario Hoffmann Oh nice it works. My thinking was just a bit wrong and there was a little bug too. Thanks emard ecp5pll has possibility for fine-precision phase adjustment but this simple BTN module doesn't generate proper phaseloadreg signal https://github.com/emard/ulx3s-misc/blob/master/examples/sdram/memtest_mister/hdl/btn_ecp5pll_phase.v#L51 TODOtry various projects for ulx3s |
