targets/colorlight_5a_75b: switch to SoCCore, CPU and Etherbone working :)
...
Tested with:
./colorlight_5a_75b.py --cpu-type=picorv32 --uart-name=crossover --with-etherbone --csr-csv=csr.csv
Load with following script:
#!/usr/bin/env python3
# Load ---------------------------------------------------------------------------------------------
def load():
import os
f = open("openocd.cfg", "w")
f.write(
"""

exit()
if __name__ == "__main__":
load()
Then start lxserver:
lxserver --udp
And run following script:
#!/usr/bin/env python3
import sys
from litex import RemoteClient
wb = RemoteClient()
wb.open()
# # #
while True:
if wb.regs.uart_xover_rxempty.read() == 0:
print(chr(wb.regs.uart_xover_rxtx.read()), end="")
sys.stdout.flush()
# # #
wb.close()

Add the Hackaday Supercon 2019 badge which has an ECP5 FPGA:
https://hackaday.io/project/167255-2019-hackaday-superconference-badge
These changes are from Michael Welling's fork:
https://github.com/mwelling/linux-on-litex-vexriscv
During Supercon, we trying two approaches:
- use the built-in 16MB QSPI SRAM
- use add-on cartiridge with 32MB SDRAM by Jacob Creedon
We were not able to get the QSPI SRAM working so I've removed
those changes, and I have just added the changes that are needed
to boot Linux with the 32MB SDRAM.
Thanks to Jacob Creedon, Greg Davill and Tim Ansell who helped debug.
KiCad design files for the SDRAM cartridge are available at:
https://github.com/jcreedon/dram-cart/
The SDRAM cartridge PCB is shared at:
