I need (eventually) to write the boot loader in to some 328P CPUs. I have a USBasp isp programmer, and UECIDE stable seems to recognize it as a possible programmer (not that I know how to either find an appropriate boot loader hex file nor how to make USBasp write it . the arduino site seems to say do this magical incantation and all will be well ) but pre4 only has ardude as the programmer. That works fine for the Uno (which already has a boot loader) and I know that the USBasp uses avrdude to do the work, will pre4 magically figure out that its there or is there more configuration that needs to go in to pre4? When I manage to figure out how to find and program boot code I can use stable so this isn't a big issue, more of a "here is something that may be missing in pre4". If there are instructions on writing boot code to a 328p using UECIDE around I couldn't find them with a search and would appreciate a pointer. From the arduino site it isn't clear to me (yet at least) if boot code is CPU or board specific. I'd expect not, but with it all being done under the covers in a "just do these steps and all will be well" way I don't yet know.
