Does PSNee need to be flashed via SPI for a PU-7 board?

[dazzaXx]

Hi, just wondering if SPI flashing is needed for a PU-7 board, I have an Arduino Nano on the way and noticed some mentions of SPI flashing the comments of the .ino code file as well as around the web, I presume that is for the "PM-41 patching" portion but I just wanted to double check that it is fine to upload the code via the usb port.

Thanks!

The best is always to flash in isp, this eliminates the boot code.

The easiest way to do this is to transform an Arduino into an ISP programmer, with the Arduino as ISP sketch

Do you have any recommendations for SPI Programmer sketches?

EDIT: Apologies, I know what you mean now.

The one that is available in the Arduino ;)

Thank you, I'm a bit of a noob when it comes to arduino and ive never used an ISP flasher before, i've only used the upload button in the IDE xD

Hi, i've just finished making a ISP flasher with my spare mega2560 I had lying around and tested flashing another arduino with it and it finally works! (I'm not a coder at all so it took me HOURS to figure it out)

So for now i'll close this issue so it's not left open. Now it's ready for when my nano arrives for PsNee!

Thanks for the help mate, I really do appreciate the help and tips. 👍

two little extra tips, using the ISP you can install the bootloader (in Arduino choose the right card, and in the options installed the bootloader) installing the bootloader with Arduino modifies part of the registers (often called fuse ) which sometimes allows the Attiny to work correctly

Is that needed for a Nano? I know when you flash with ISP it removes the bootloader for faster boot times which is needed for this use of PsNee, is the Burn Bootloader option for say if I wanted to upload normally to it again?

[kalymos]

Normally it's not necessary for a Nano, and for the rest that's it

Hi me again, i've recieved the nano but it has a 328PB processor in it, and I cannot flash it by just choosing the nano option since it expects just a 328P, i installed MiniCore and managed to flash it with that as it has a PB variant option. Are these settings appropriate?

Or is there more preferred route to flashing it?

Thank you!

EDIT: This is also the output, not wired up to the PS1 yet tho.
