Holybro HK 328P Uploading Errors

[jgarnham47]

Just received a new board from HK today and I can't get it to upload new code. I am using 1.0.1 of the compiler and R1240 code (also tried 2.1). I constantly get standard "avrdude: stk500_getsync(): not in sync: resp=0x00" errors.

I have been using a Paris V3 board for a year, probably programmed it 50 times without any problems using separate FTDI board, this integrated one just does not want to play ball.

Probably not relevant but I have a 3 cell lipo into 5V UBEC, into a 9 channel orange receiver into the MW board. With or without external power, it just won't flash.

Any advice or tips to help me through this please?

Sorry people, eventually found the solution to the problem ... there appears to be an issue connecting anything to Aux2 (1, 3 and 4 are okay) and because I automatically connected a 9 channel receiver it prevented programming. Having worked that out, I found this thread on RC groups, which I will tag here for anybody reading this in the future. Next issue Crius OLED reset problem ...

I had the same issue, but with the Crius Lite board.

Your solution plus a bit extra solved it for me, too. In addition to removing the AUX2 connection to the receiver, I had to disconnect power to the receiver and my attached UART bluetooth module altogether. Once it was just the board all on its own, things worked perfectly. I also had the 'arduino pro or pro mini 5V, 16Mhz with Atmega328p' selected for my board option in Arduino 1.0.1 and I chose the USBasp for my programmer.
