Just wanted to say a thank you for all your work here.. I'm way down the ladder as far as the capabilities that exist here are concerned and all this work has been a great help for me.
Played with the Maple minis which have been great and now have some HY-Tinys going just fine.
Had a bit of work to do as far as understanding how to get the bootloader on, but as I had an ST-Link available to me and some details here, I pulled it together slowly.
In the end it was quite simple really, and the Tiny worked straight away in the Arduino environment.
Pin1 STLink to Tiny 3V3
Pin3 STLink to Tiny GND
Pin7 STLink to Tiny SWDIO
Pin9 STLink to Tiny SWCLK
Pin15 STLink to Tiny RST
Got STLink Utility from ST.com site, and the bootloader from your link here.
Connect Link and Tiny. Power Tiny and Link via USB's. Open ST link utility. Hit Connect. Load up bootloader binary.
Select Prog & Verify. Addresses etc default correctly (0x08000000), so hit Start and 3 seconds later all is done.
Disconnect, reset and load Blink file, use generic STM32F103T, change pin to PA1 (as mentioned previously), and bang.. all done.
I only include the above here just in case it may be of help to someone
Thanks again .....
