Both Oscilators fine
I see echo on terminal.
I steel can program from AVR ISP v3.2 both chips:
stk500boot_v2_mega2560.hex or temp hex (2560 chip works good) from ard. ide and Arduino-usbserial-mega.hex vyrifing ok.
When erase 2560 (AVR ISP) leds down. When load bootloader led13 blinking 10Hz.
But cant program from IDE:
write bootloader - log "isp not in sync"
write sketch - tx and rx blinking1-3 times per some seconds (10-50) ...and finaly it log "timeout".
Can u help me?
