I have a 40X1 on a pcb that downloads/sertxd backs and runs its the program fine/solid with the download cable attached.
Remove the cable and the program wont run.
I have decoupling caps on the power supply pins. 100n & 10n. I have tried putting a 10n cap on the reset pin. Im running the 40X1 on around 2.7V so I thought to try a lower value pull up R on the reset, (1K) all to no avail.
Can anyone give me any pointers?
