Toot

Written by Mike Bell on 2025-01-05 at 22:57

TinyQV on #TinyTapeout 6 update: I have a CoreMark! 4.969 isn't going to be making any headlines, but it will be interesting to compare to other TinyTapeout SoCs.

And I have a #MicroPython port up and running! GPIO and SPI work, as does mpremote (but not Thonny for some reason). Next on the list will be trying to mount a filesystem on an SD card over SPI.

I'm also interested in making a filesystem in the PSRAM - TinyQV doesn't support writing to flash, but having a local filesystem in RAM could be useful - and having a PSRAM filesystem option would be quite handy with various RP2350 MicroPython projects too...

@mike I was blown away for a second but then realised you did not mean CoreMark/MHz 😅

@wren6991 Yeah, sadly not. Main bottleneck is having no instruction cache at all, and the flash speed is rather limited because the TT outputs are max 33MHz.

Hoping to get DTR going for the next tapeout which should help quite a bit.
