No more fighting with a loose TTL-USB-cables: I have USB hub shield with USB-to-UART port :-) Or two of these: one for Raspberry Pi 3B+ and other for VisionFive 2 RISC-V SBC (in the pic). Need to still pile a TPM2 chip to the pins on top of the shield and hopefully it will still work. #arm #riscv #visionfive2 #raspberrypi

Also got this display, right now it is connected to a 7th gen NUC that use to test all x86 patches (because it has full sgx2 support). Display cost less than 50 euros and it is super handy for kernel testing.

Super-nice additional benefit of this shield: one cable less. Before I needed power cable and USB-TTL for TTY. Now only by connecting micro-USB to the shield it draws the power and provides serial access.

The screenshot has unmodified #BuildRoot master branch version built with visionfive2_defconfig. Seems to be much more stable than lean, at least for the kernel development, than the official SDK, which is quite scary looking construction tbh :-)

The USB HAT with UART-micro-USB bridge I got is https://www.amazon.de/dp/B072Q5S1XH?psc=1&ref=ppx_yo2ov_dt_b_product_details. I ordered couple of these (other for raspberry pi 400).

huge workflow improvements with less than 100 EUR investment :-)
