That's a great app but is it possible to add auto upload option to bw16 board Update: Thanks for your quick response I mean upload without press burn and rst buttons to enter upload mode, it's like Arduino ide do for bw16 type c board

Hi thanks, sorry what do you mean exactly ? Bw16 flasher uses automatic bootloader and upload files you provide at the offset you want (in general from 0x08000000 ...) Update: it is already the case, be sure "bootloader auto" switch is ON, unplug/plug again if needed and just hit flash button... Please send me a mail if you face any issue

Please add Realtek BW16 programming support . Is it never possible to program this with an Android app?

Hi and thank you. The BW16 uses a different flashing protocol and so this app cannot support it. Sorry. Edit: not impossible, just very specific. Lot of work required for just one board. Edit New update take the BW16 in charge finally! Coming soon
