Add support for tinyAVR 2 Series MCU like attiny824 #268

Closed woodymgh closed 2 years ago

woodymgh commented 2 years ago

Please add support for the Attiny Boards like: attiny424 attiny426 attiny427 attiny824 attiny826 attiny827 attiny1624 attiny1626 attiny1627 attiny3224 attiny3226 attiny3227

This are upcoming great processors with many Hardware support like Timers, UARTS, 12Bit ADC, TWI, SPI and low Cost. https://www.microchip.com/en-us/product/ATtiny824

When I'm trying to compile for Attiny424 I am getting the following error. Is there still something missing or am I doing something wrong?

my platformio.ini looks like this, and I removed the .platformio/{.cache,packages} directories before building: 

[env:ATtiny424]
platform = https://github.com/platformio/platform-atmelmegaavr.git
; platform = atmelmegaavr
board = ATtiny424
framework = arduino

Hello,

the same issue here for attiny824 without arduino framework:

Processing ATtiny824 (platform: https://github.com/platformio/platform-atmelmegaavr.git; board: ATtiny824)

Verbose mode can be enabled via -v, --verbose option CONFIGURATION: https://docs.platformio.org/page/boards/atmelmegaavr/ATtiny824.html PLATFORM: Atmel megaAVR (1.5.0+sha.de9877b) > ATtiny824 HARDWARE: ATTINY824 16MHz, 1KB RAM, 8KB Flash PACKAGES:

is this the wrong toolchain ?

platformio.ini:

[env:ATtiny824] ; platform = atmelavr platform = https://github.com/platformio/platform-atmelmegaavr.git ; board = attiny45 board = ATtiny824 ; framework = arduino

Hello,

i got it's working (to compile, i can't test if its wright)

i have changed the platformio.ini to:

[env:ATtiny824] ; platform = atmelavr platform = https://github.com/platformio/platform-atmelmegaavr.git ; board = attiny45 board = ATtiny824 ; framework = arduino

BUILD_FLAGS = -Battiny_dfp/gcc/dev/attiny824 -Iattiny_dfp/include/

extra_scripts = extra_script.py

in the dir where platformio.ini is located i create extra_script.py with this content:

Import("env")

#

Dump build environment (for debug)

print(env.Dump())

#

env.Append( LINKFLAGS=[ "-Battiny_dfp/gcc/dev/attiny824" ] )

i go to https://packs.download.microchip.com/ and download the pack for
Microchip ATtiny Series Device Support

i rename the extension from ".atpack" to ".zip" now i unzip the pack. i rename the dir with the pack to attiny_dfp i move this dir (attiny_dfp) to the dir where platformio.ini is located

now i can compile

I have forgot:

i have changed the ldscript (because it's wrong) in the file .platformio/packages/toolchain-atmelavr(version what you use)/avr/lib/ldscripts/avrxmega3.xn

replace data (rw!x) : ORIGIN = 0x802000, LENGTH = DATA_REGION_LENGTH

with data (rw!x) : ORIGIN = DATA_REGION_ORIGIN, LENGTH = DATA_REGION_LENGTH
