Yet another atmega1284p based arduino- Recomendations for bootloader ?

-

hi all,

i ve finished constructing new standalone arduino based system.

main features:

dual atmega 32u4 or atmega1284p support (either chip can soldered on pcb on separate footprints)

onboard rs232 interface
onboard rs485 interface
onboard switching power supply 10-24v ac or 12-30v dc supply (supplies 12v,5v , 3.3v)
onboard serial eeprom (2 ics)
onboard relay driver along 6 power relays (mains)
onboard socket nrf24 radio comms
i2c temperature sensor , i2c interface expansion available
number of expansion headers available (8 bit digital, leds, i2c, etc)

all above accommodated in double sided pcb measuring 10x8cm designed fit in din rail mounted box if required.

photos follow soon..

at point trying choose suitable bootloader atmega1284p. first time using chip , have no experience available bootloaders. ve been using 32u4 arduino micro bootloader far.


could please make recommendations suitable bootloader?
 



the optiboot.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
