Error codes when compiling to target

[Billduck1302]

I get this response: I was wondering if there is a guide as to error interpretation. I might add that if no UNO is plugged in, I only get the last code. I have selected, in Project options, the correct programming port. I am wondering if I have the incorrect version of the UNO.
""avrdude.exe: stk500_loadaddr(): (a) protocol error, expect=0x14, resp=0x08

avrdude.exe: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x24
#avrdude.exe: stk500_cmd(): programmer is out of sync

Error returned from [avrdude]

C:\ProgramData\MatrixTSL\FlowcodeV11\FCD\AVR\batchfiles\avrc_arduinoA.bat reported error code 0x1

If I search for that "avrdude.exe: stk500_loadaddr(): (a) protocol error, expect=0x14, resp=0x08" error on the web, I get the following suggestions:

• checking your USB cable/port
• ensuring the correct board/port is selected
• closing other serial programs
• pressing the board's reset button just before upload

There's also this post in our old forums that suggests a solution (in German) for a similar issue:
