Not sure how I thought flash operations were previously working as there
were many bugs I had to correct to support flash operations properly.
Operations module appears to be working so far, still need to pass
functions to operation module.
Flash operations verify PRG-ROM 32KB writes working with file comparison.
Currently dependent on extra buffer status reads to delay next buffer.
I think the write operation is taking longer than the usb load operation.
Potentially due to slow code of operation module, but also possible I
had only been testing with slow eeepc linux machine previously. Perhaps
combination of both.
Still need to correct issue so added buff status delays aren't needed.
buffer manager should be able to key off of status==USB_FULL but that
doesn't seem to work. When trying I don't always get the same number of
buffers to get flashed so appear to have a race condition or something
not properly intialized..?
Need sort out sending of USB STALL if buffer isn't ready to be loaded yet.
This commit is mainly for documentation/reference purposes as things are
kind of working, but buggy/unstable.
AVR Memory Usage
----------------
Device: atmega164a
Program: 6486 bytes (39.6% Full)
(.text + .data + .bootloader)
Data: 679 bytes (66.3% Full)
(.data + .bss + .noinit)
Things appear to be working with some early testing. Assumption that oper_info elements
are aligned in SRAM linearly appears to hold true. Researching this I found it probably
was true, but can't be certain esp if gets changed in the future to not be purely 8byte
sized elements.
Still need to provide means to decode function numbers info function pointers.
