flashing m328p au(smd) with optiboot stk500v2 failure

Other Hardware 3rd Party Boards
1

I have searched as much as possible about this and have come to the convolution there is something wrong with my pcb design. To me it looks like a striped down version of the sparkfun pro mini 5v 16mHz dev board. I double checked all my traces and components and found everything looks good as far as i can tell.

I am using a olimex stx500v2 clone. and tested by flashing a virgin chip on a uno board successfully. I try to do the same with my 328p on my custom board and cannot connect.

unknown status 0x80
unknown status 0xc9
initialization failed
invalid device id 0x000000

So i thought i had a bad chip. reflowed a new one on and same thing. Thought it was a bad resonator (16mHz btw), reflowed that as well, and still got nothing.

pulled a sparkfun pro mini out, took off the processor and the resonator and reflowed my parts on and voila i was able to upload the boot loader.

I have continuity everywhere i am supposed to. double checked my reset is pulled high. have a constant 5.0v where there is suppose to be power. All grounds check good. I can't see where i screwed up. So i am hopeing someone here will be able to see it.

Here is the avrdude output

Um. Optiboot implements STK500v1 only, and a tiny subset that has become incompatible with newer versions of avrdude at that. Try using "-c arduino" instead...

Edit: oops; I guess you're using a separate stk500 programmer (but don't they all run at 115200bps?) The avdrude output looks like you are failing to communicate with the programmer at all, which shouldn't be dependent on the board being correct. Do you get different behavior if you simply disconnect the programmer from the target board?

Your reset pull-up resistor is too low. It should be at least 10K ohms. It's probably not allowing your programmer to pull the reset line down low enough for programming.

Thanks for replying.

if i leave the programmer disconnected (just usb to programmer, no arduino) then it will tell me there is 0.00 target vcc. When it is connected to the arduino then it shows target vcc is 5.0.

Also i know the programmer works with that chip because i removed the 328p from the pro mini and put my hardware and can upload the boot loader. I am using the same chip (atmega328p-au), but just wanted to make sure the chip and resonator was functional.

There is a specific problem with my pcb and/ or the resistors and/or capacitors i have chosen. i just can not figure out what.

Hiduino you are absolutely correct. I don't know how i missed that....
I will fix that right now.

It was the 10k resistor.

Double checked all the traces and voltage values, didn't check component values.

Thank you! This was driving me nuts.

I don't remember by heart but I thought next to DTR is arduino's TX, then RX, not the other way around, at least for sparkfun FTDI adapters.

Yes, it looks like that's the way he has it. Looking at the PCB it's going to the right pins. Tx and Rx are crossed correctly.
