Hi,
i try to upgrade my OS2.3 System to FW 2.19(4).
i get following message:./avrdude -C ./avrdude.conf -c arduino -p m1284p -P /dev/tty.wchusbserial1410 -U flash:w:os_219_4.hex
-bash: ./avrdude: Bad CPU type in executableany idea? is that a problem of the downloaded FW file?
I have no idea: this doesn’t have to do with the firmware, it has to do with your operating system. I just googled “Bad CPU type in executable” and found mentions of this error in Catalina. You can google it yourself and check solutions.
its looks loks like that this avrdude is 32 Bit executable. right?
file ./avrdude
./avrdude: Mach-O universal binary with 2 architectures: [i386:Mach-O executable i386] [ppc:Mach-O executable ppc]
./avrdude (for architecture i386): Mach-O executable i386
./avrdude (for architecture ppc): Mach-O executable ppcmacOS Catalina (10.15) dropped support for 32-bit executables 🙁

is there any workaround. i guess i`m not the only user which runs MacOS in that version.
I found a solution. you need to use newer avrdude version.
I useed that one http://downloads.arduino.cc/tools/avrdude-6.3.0-arduino17-x86_64-apple-darwin12.tar.bz2 and it works.
You only need to change the command a bit as the conf file is in that zip on different folder../avrdude -C ../etc/avrdude.conf -c arduino -p m1284p -P /dev/tty.wchusbserial1410 -U flash:w:os_219_4.hex
maybe Ray can change the documentation for FW updates on MAC and include that informations.
Right, it looks like this has to do with Catalina dropping support for 32-bit programs. Yes we will update the instructions shortly. Thanks for reporting.
