I have Gemini CLI to build an ARM64 emulator from scratch and boot Linux to shell. Gemini has done it in 4.5 days (across 2 weeks). I’m amazed by Gemini’s ability in embedded programming world.

Wrote a M68020 CPU emulator for Tektronix TDS820 6GHz oscilloscope. Almost reach the shell prompt of VxWorks 4.0.2 OS. Ran out of time.

With Codex, Claude, Gemini’s help, finally have come down this point…….. Fully recreated by AI from scratch, Tektronix TDS820, LeCroy WaveJet 324, and TDS1012 oscilloscope emulators. Original firmwares (I own these scopes) running on CPU emulators and with SDL wired up to their output.

FPGAマガジン特別版の味わい AIで開発特集はチャット形式からチーム形式での開発で検証ループを自動で回して…ってもうFPGAだからってのは関係ないな。大事なのは提示する仕様をきちんと明文化できるか。仕様が分からないものを作る場合はどうすればいいんだ

Connected 11 @AMD Kintex-7 FPGA cards running @apexcompute Unified Engine accelerator IP to test some big models on these cheap cards. 44 GB DDR3 with 22 Unified Engine cores totaling around 557 BF16 GFLOPs.

Dělat FPGA s AI když všemu úplně nemusím rozumět je radost. Litex znám, FPGA a ZephyrRTOS taky. Tak jsem to navajboval na Cyclone 10 LP s 8MB SDRAM. Po startu se nakonfiguruje FPGA s Risc-V, z SPI FLASH se do SDRAM nakopíruje BIOS+Zephyr a prostě běží @enjoy_digital @ZephyrIoT

Spotted over on the @RadionaOrg #Gatemate FPGA Discord channel - the @intergalaktikEU ULX5M-GS boards! Ready for shipment.😎 Similar to the ULX4M (which instead has ECP5), both ride in any Raspberry Pi CM4 carrier. Nice boards 😍

White Rabbit project is awesome! But it was locked to uRV CPU and had to execute CPU firmware code from BRAM, which was not flexible and also not suitable for small FPGAs... This restriction has just been removed with recent LiteX-WR-NIC work: - Can now use one of the LiteX supported RISC-V CPU (ex VexRiscv). - Can now execute code from internal or external RAM (ex HyperRAM). github.com/enjoy-digital/lit…

Everyone wants founders to be bold and brave, but not enough people expect the same from investors If your backers don’t have the balls to go alongside you no matter what, it’s just generational aura debt Respect to the VCs with aura, they don’t get enough credit

Made a breakout for an SSM2518 audio amp in a 0.5mm pitch QFN package that can push 2W per channel into a 4 ohm load on a 5V supply. Connected it up to the jetson, and configured the DTB for I2S output, and it works.. sounds surprisingly good too. They expose a register set for config and gain/attenuation over an I2C interface, which connects up to the Stemma QT port
