Flashing more than 128kb into an Atmega2560 MCU...what programmer?

-

hi,

recently read problems flash more 128kb atmega2560, due
to change 2 bit counter (up 128kb) 3 bit counter (from 128kb onwards
til 256kb).

i think manpage of avrdude says:
 atmega2560, atmega2561
                               flash addressing above 128 kb not supported programming
                               hardware.  known work jtag2, stk500v2, , bit-bang pro‐
                               grammers.

the genuine atmel/microchip hardware "feels" little expensive...jtag complicated (and expensive) ... , counts "bitbanging programmer"...
i know bitbanging (i think), using gpios bitbanging spi instead hardware spi reason,
why more 128kb can programmed?

normally use simple ftdi-cable , bootloader flash stuff or buspirate acts
as isp in case (bootloader flashing preferred, cause isp overwrites bootloader each time...).

am able flash more 128kb hardware?
what need else?

thanks lot in advance!
cheers

buy couple of cheap usbasp programmers.

change firmware bperrybap/usbasp/tree/1.06-alpha.

works great.

Flip address is out of range arduino uno r3

hello  guy, trying flash firmware on arduino uno rev3 atmega 16u2 using atmel flip. whenever try , import .hex file program, throws error " address out of range ." have looked around online , haven't found solution. , info helpful. here hex file : https://github.com/nicohood/hoodloader2/blob/master/avr/bootloaders/hexfiles/hoodloader2_0_5_uno_atmega16u2.hex its using arduino uno hid Arduino Forum > Using Arduino > Installation & Troubleshooting > Flip address is out of range arduino uno r3 arduino

Arduino Uno not uploading

hi guys, so, have arduino uno r3 (not wired thing) when try upload sketch (even empty sketch) first takes long in "uploading..." comes error: arduino: 1.8.0 (windows 10), board: "arduino/genuino uno" sketch uses 444 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x9f avrdude...

Indesign and MathType fonts

-
i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
