Put bunch of notes in Readme.txt on how to update device firmware to
v2.3 using dfusedemo. Anyone with a device currently in their hands
will want to update to this latest version using the dfusedemo
instructions there. Or the AVR instructions if you have an old kazzo.
For devices shipping after Dec 1st 2018 I will be flashing this latest
v2.3 firmware which has it's own firmware updater so the INLretro host
software can easily and seamlessly update the firmware for you without
any external software, switch or jumper operation on the PCB.
This update also includes some power functions in the bootloader
dictionary. Can now make direct read/write access to the entire ARM
memory space. Maybe I'll add this to the AVR someday..?
Having this previously would have actually allowed me to bootstrap
a switchless bootloader without dfuse.. ahh well...
Also turned the watchdog timer on for the STM32 build finally.
Requires refreshing every ~1sec, currently only done in the main.
Added application versioning to address 0x08000800 in the binary.
Couldn't get the linker script to do this for me for some reason.
So for now I just manually put it in the binary file.
The fwupdate.lua script has a lot more checks now. Uses the new
bootloader dict functions to dump device firmware and make sure
all looks good before it starts erasing firmware.
Haven't done much testing with the current AVR build. Got a report
there was a problem with UNROM flashing, will have to check that out.
Done with the firmware for awhile now hopefully. Need to clean up some
things with the main program & inlretro.lua script. Start making better
use of some recent contributions by several gracious people.
Maybe I'll get going on gameboy, GBA, & sega soon.. Got a ton of
NESmaker devices to push out the door now with this latest build. So
might be slow for a bit..
underlying hardware/mcu. Created avr_gpio.h to define AVR pin registers
in a struct fashion similar to what's common with ARM code. Doing that
makes things much easier to abstract in pin macro 'functions'.
Added define to Makefiles that flags pinport_al.h which board is targetted
for build.
Tested and able to turn on/off and pull-up LED on all 3 builds.
Two different Makefiles, specify which with -f file flag:
make -f Make_avr clean program
make -f Make_stm clean program
made release dir to put released .hex firmware files
Need to make separate avr build folder
Need to make one master Makefile that calls one of the other makefiles as
instructed.
Currently device is recognized by PC but does nothing else other than
being recognized by app during connection process:
