I hope this is the correct forum for this post...

 

I was reviewing the file SCI.c for the BDM firmware.  I think that because a preIncrement is used to place a char in the txbuffer : U8 tPtr = txTail+1; then a preIncrement operator should be used to take it off :  ch = txBuffer[++txHead]; not ch = txBuffer[txHead++];  Both txTail and txHead start as 0.
