Details:
Hello,
I installed arduino 1.6.13 (which embed avrdude 6.3) on a Raspberry Pi 3
(2016-11-25-raspbian-jessie).
I correctly program my arduino Nano when I connect the Nano on a USB port of
the RPI3.
But, if i connect the RPI3 on a USB Hub which is connected to the RPI3, the
upload fails:
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e950f (probably m328p)
avrdude: stk500_cmd(): programmer is out of sync
I tried many scenario to understand the problem:
- I installed the same configuration on a RPI1 and on a RPI2, everything works
correctly on both.
- I set the speed of my RPI3 to 500Mhz and everything works correcly !
It seems that this bug is linked to latency/timing problems
Regards,
LB
