This board from @LambdaConcept ecpix-5 based ecp5-5G is one of my craziest boards I have.
According to #litex mem_test I successfully added the @1bitsquared HyperRAM pmod to the @LambdaConcept ECPIX-5 litex SOC! (link to files next)
I'm super happy to welcome my very first corporate PCILeech sponsor - LambdaConcept! Thank You @LambdaConcept for sponsoring PCILeech development 💖 After being sold out for a long time LambdaConcept finally have new ScreamerR04 back in stock! shop.lambdaconcept.com
I don't wanted to write a i2c controller to configure the it6613. So I got the i2c init c code from @ultraembedded and modified it to generate a rom table from it. This rom table speaks i2c to initialize the it6613 hdmi chip @ecpix5 from @LambdaConcept ! ProofOfConcept
It works niw I took your c code and modified it to generate a verilog rom table to initialize the it6613 via i2c without softcpu. Funny to have i2c with a rom table :) github.com/splinedrive/ha…

Quick test of gsomlo's Linux-on-LiteX-Rocket on ECP5 with 64-bit 5.11.0-rc4 RISC-V Linux kernel and rootfs on SDCard: github.com/litex-hub/linu…
Oh, a new #fpga board!! (#ECPIX5 by @LambdaConcept with a 85F ECP5 by @latticesemi) Time for a new #Silice framework! This was the perfect opportunity to start a tutorial on adding new board: github.com/sylefeb/Silice…, work in progress)
Tested on freshly released @Lambdaconcept's ECPIX-5 with SDCard and Ethernet support: ./make.py --board=ecpix5 --build --load, prepare and insert the SDCard and it should boot :)
99€ for a general purpose ECP5-5G (from @latticesemi) board with 8 PMODS, DDR3 RAM, GB Ethernet, microSD UHS-2, HDMI, SATA, USB-C, RGB leds.! Perfect for learning nMigen! (If you find cheaper, just let us know😉) shop.lambdaconcept.com/home/46-1-ecpi…
PCILeech support for AMD Ryzen coming along much more nicely than previously thought. Release already in 1-2 weeks! This is me dumping memory really fast from my Ryzen 3900X with the ScreamerM2. It's super stable 😀
DOOM running on my homemade RISC-V, DDR3 and DVI framebuffer IPs on the @LambdaConcept ECPIX-5! Need more MHz as 25 is not enough! I am burning cycles scaling from 320x200 to 640x400 in SW though (which the FPGA fabric would be much better at)!
First attempt at a DDR3 controller from scratch is working! My RISC-V CPU, DVI framebuffer and DDR3 designs working together to play a GIF on the @LambdaConcept ECPIX-5 @ 640x480x60Hz. The CPU is not doing much - just cycling through the pre-decoded frames at the right rate.
Got myself a Ryzen 3900x for PCILeech testing today! And a very nice ScreamerM2 with USB-C. Now I'll finally be able to fix the AMD issues I've been having😀
Just got hold of a @LambdaConcept ECPIX-5. First time using the open-source toolchain #Yosys + #Nextpnr, first time using #openFPGALoader, and first time ever using a @latticesemi FPGA. LEDs already flashing. 1hr start to finish - and no 10GB Xilinx downloads required 😀 Love it!
A project from last month. Taking the @LambdaConcept #USB2Sniffer board and turning it into a RISC-V Linux single-board computer (with USB host). github.com/ultraembedded/… All Verilog IPs are posted on Github (CPU, SoC, USB). Really wish it had a HDMI socket or just 8 spare I/Os!
Helping @LambdaConcept doing the ECPIX-5 board bringup with LiteX/LiteDRAM, Linux booting on the first try :)
