Newcomer: Blinker example does not work

Hello,

The blinker example is my first test with Maixduino. After the flash, the following messages appear:

Downloading ISP: |=================================================================| 100.0% 10kiB/s
[INFO] Booting From 0x80000000
[INFO] Wait For 0.1 second for ISP to Boot
[INFO] Boot to Flashmode Successfully
[INFO] Selected Baudrate: 2000000
[INFO] Baudrate changed, greeting with ISP again …
[WARN] Timeout Error, retrying…
[WARN] Timeout Error, retrying…

It stops with error:
[ERROR] Failed to Connect to K210’s Stub
[ERROR] Failed to Connect to K210’s Stub

I have installed Arduino 1.8.9 and v0.3.8.
As I understand is the Maixduino board not yet supported but it seems to be in v0.3.9. How to get this release into the Arduino IDE?

Any hint is very welcome.
Regards Walter

I haven’t got that board, but with my board upload errors happen often. Does trying to upload it a couple of times help?

Hello Sentry,

Many thanks for your quick answer. I repeated Blinker several times, but with a speed of 1.5 Mega it runs a little further:

But no blinking and it did not show a print message from the setup routine.

Best regards Walter

I tried the classic Arduino Blink example, it blinks twice and stops.
Very strange.

OK, my fault. After I press the reset button after flash, it works.

Thanks for your help.
