QUESTION

ATmega328p - Expected unqualified-id before 'volatile'

Asked 2020-Oct-09 at 21:12

I'm working on a custom bootloader for OTA updates for my ATmega328p. I'm taking help from the Optiboot bootloader's code from Arduino and for the USART part, I have written a custom header file for handling USART comm. part. Here's is the code (check code basically to test the logic)-

Install optiboot

You do NOT need to "install" Optiboot if you are trying to update an installed platform that already uses some form of Optiboot. In fact, you should almost certainly NOT install Optiboot using the board manager. The Optiboot GitHub repository these days is mostly useful as a source-code repository, for anyone who needs to make a highly customized version for some reason. Or an improvement to Optiboot itself. Most end users should find a supported "Arduino Core" that includes Optiboot for their desired target, and install that. Many such cores are provided by the hardware vendor, and they'll include Board definitions, Variant files, and Arduino core code needed to support the target as well as one or more Optiboot .hex files that should work.
MegaCore by MCUdude Supports large AVRs like ATmega128, ATmega640, ATmega1280, ATmega1281, ATmega2560 and ATmega2561.
MightyCore by MCUdude Supports most 40pin AVRs including ATmega1284, ATmega644, ATmega324, ATmega32, and ATmega8535.
MiniCore by MCUdude Supports most 28pin ATmega AVRs, including the CPUs used by Uno/etc as well as the new CPUs like the ATmega328PB.
MajorCore by MCUdude Supports a couple of relatively obsolete large AVRs, like ATmega8515 and ATmega162.
ATTinyCore by Spence Konde Supports many ATtiny AVRs, including ATtiny85, ATtiny1634, ATtiny84, and ATtiny841.
MegaCoreX by MCUdude Supports the Mega-0 Series AVRs (notably the ATmega480x and ATmega320x) (Using Optiboot_X.)
megaTinyCore by Spence Konde Supports many of the Tiny-0 and Tiny-1 series AVR chips (using Optiboot_X.)
Find the desired Optiboot release on the Optiboot Release page.
Use the "Copy link address" feature of your browser to copy the URL of the associated .json file.
Paste this URL into the "Additional Boards Manager URLs" field in the Arduino IDE "Preferences" pane. (Separate it from other URLs that might be present with a comma or click the icon to the right of the field to insert it on a new line.)
After closing the Preferences window, the Tools/Boards/Boards Manager menu should include an entry for that version of Optiboot. Select that entry and click the Install button.
