Extremely long "Resetting COM" stage while sketch upload #1654

Closed jaszczurtd closed 1 year ago

jaszczurtd commented 1 year ago

Platform: win10 + AMD Ryzen 5 / 32GB IDE: Arduino 2.1.1 Boards Raspberry pi pico/ pi pico W USB stack: PicoSDK

Issue started to show up after upgrade from core 3.0.0 to the current one (3.3.2). After downgrading to 3.0.0 everything seems to be OK again.

Resetting COM6 <---- this stage takes forever Converting to uf2, output size: 1119744, start address: 0x2000 Scanning for RP2040 devices Flashing E: (RPI-RP2)

If pico is in uf2-mode (after rebooting with button pressed), upload takes no time.

@earlephilhower why this issue was closed without any comment? Unfortunately this issue is still there. However, I noticed, that printing a lot of debug via Serial.println() causes the problem to stop. But this is not a solution...
