-SNES support for 32Byte page writes, but host lua scripts are a bit of
a mess and still need committed. Firmware isn't very clean either but
it's working..
-SEGA stuff is early and non-working. Got it working in a separate
branch which will commit shortly.
-SWIM updates for better erasing, flashing, and dumping routines
-FILES updates for jtag and some other niceties
-JTAG is working now for LC4032V & Mach-XO 256
Firmware application version #3 release
-------------------------------------------
N64 updates:
Some extra timing delays were necessary for consistent dumping.
Includes fixes for N64 dumping that proved working for me on 10+ carts I
dumped successfully. There is now a .csv in docs folder with cart size
in bytes, divide that number by 131,072 to get size in mbits for -z
flag. Includes CRC32 checksum that can be verified using HxD hex
editor. N64 file output is big-endian so it reads as it should in hex
editor which is .z64 file format. lua script updated to print out the
game name from the in rom header.
NES updates:
flashing support for quite a few different mappers including GTROM,
MMC2, MMC4, action53, easyNSF, and other tweaks to rd/wr timings.
FIRMWARE UPDATES:
inlretro2.lua script now tries to poll the firmware "application
version" and suggest updating your firmware if you're not running the
version in this release. You can always update your firmware using the
bootloader method in the readme. But there is an easier method if you
have an stm32 based device (translated: you purchased your device in
2018 or later). AND you're already running firmware version v2.3.x
simply run the new scripts which were added in this commit:
PCB version 2.0 or 2.1 (large square PCB with option for 6 connectors)
>inlretro.exe -s scripts\inlretro_inl6fwupdate.lua
PCB version 2.0N (smaller PCB with NES connector only:
>inlretro.exe -s scripts\inlretro_inlNESfwupdate.lua
Now that it's easier for the host software to detect the firmware
application version can work towards having the scripts automatically
update the device firmware for you.. But still need to implement this..
included. Not making an offical firmware release, will have to upload to
INLretro6 with fwupdate call.
The colordream firmware updates are also included. But not the host
scripts, need to clean them up a bit.
cartridge reading!
have some cleanup to do:
clean up sega dumping so don't need a page0/1
implement sega single reads
Add GBA to some of the common opcodes
dumping Don't think need addrH |= of mapper, but maybe this is key to
cleaning up first note..
gba, sega, n64 has extra NOPs, remove and test.
create pinport renames for sega pins, move mask defines to pinport.h
clean up comments for genesis page reads..
haven't done anything with save ram/flash yet, but should be able to
dump rom for any/all GBA carts now! Tested with 8Mbyte Metroid Fusion.
Took ~75sec at 107KBps
this is the verion getting flashed on all v2.0N NESmaker kits
v2.3.0 worked for basic functions, but was never shipped
Majority of effort revolved around testing mapper30 boards with the
smaller v2.0N INLretro with the NES connector alone for NESmaker kits.
added linear feedback shift register for test stream data generated
locally on the device. I'm not 100% sure if this is any faster than
pushing the actual data via USB though.. :/ It's plenty fast on the
stm32 nearly instantaneous for 32KByte. But the AVR takes a couple
sec..
Created "stuff" dictionary for things like that were I just want to add
small things and don't want to bother with a whole new dictionary.
Added file verification to the host with files.lua
Have some nes flash algos return post-written data so calling function
can decide if want to retry, fail, etc.
Changed host dictionary calls to assert instead of error because it
really shouldn't continue. I didn't see an error when sending opcode to
wrong dict and caused head banging..
fwupdate permits bytes to be skipped, or force the update. Found that
the fwupdater got assigned different addresses of ram depending on what
all other ram gets allocated to the main application
Some clean up of inlretro.lua
TODO:
host learn and keep track of the connected device.
Needed for ciccom right now, or knowing whether ciccom connection
is even present..
In the end maybe ciccom is better placed in firmware, but for small
transfers of only a few bytes it kinda makes sense to keep on the host.
Pinport gets quite messy with these made up pin names when really all I
want to do is toggle a specific pin on the NES connector. So maybe some
double mappings would actually be okay, need to rethink that..
create different flash modes that either keep going, retry, or error
depending on the goal of the flash operation. Fanout the return value
from flash algos to all of them.
have fwupdate assigned a specific area of ram so the ram pointer doesn't
change between builds. Okay to ignore for now.
Realized can have STM32F070C6 devices execute bootloader by erasing all
the flash or perhaps even just the first word of flash according at
AN2606. This wouldn't work for RB devices though. This could be done
through the bootloader dict
