Serial1 - Strange Behavior

Good evening, I''m using a serial1 and connected to it i ve my shield that i've done for send out message ...

but when i've connect it i cannot program my arduino ... with sync issues ...

and if i detach my shield i can program it ... when i connect it again my arduino start to reset each time ...

what could related ? for sure is related to my shield but could be the issues that cause the reset ?

is there someone that has encountered this issues ?

Thanks Andrea

Can you post a complete schematic of your shield so we can see how it works with the Mega?

Hi the fact, is working like normal tx / rx crossed ... with virtual wire library for example no issues with that ... but i would like to do a test with serial port,
