Problem with programming atmega328 using ch340

[lhbijfsa]

I have a little pcb which uses atmega328 and i've been trying to program it but i constantly get error

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

which 100% works because i successfully programmed arduino pro mini (atmega328 5v) with it, but for some reason i can't program the uc on my pcb, schematic is the following

I tried almost everything all the connections are correct (rx to tx, rx to tx), i chose arduino pro mini (atmega328 5v) and avrisp as programmer, any idea what might be wrong?, the only thing i can try is replace the uc, do you think the aref connected directly to 5v instead through a 100nf capacitor might be a problem

i am using this programmer and i soldered a wire to dtr pin of the ic and connected it to reset pin of the uc

do you have a boot loader in your atmega328?

[groundFungus]

Your schematic is missing the required decoupling caps. 0.1uF from Vcc to ground and 0.1uF from AVcc to ground.

Not a source of your trouble, but Aref should not be tied to Vcc. Tie Aref to ground through a 0.1uF cap.

Totally forgot about bootloader, that was the problem, now it uploads without a problem, thanks a lot

we've all been there I'm sure

have fun

And can we upload the code to the microcontroller using the IDE by bootloader

[groundFungus]

Not sure what you mean. If the right bootloader is installed, you can upload code via the serial port.
