Re: USB bootloaderhid with Atmega128

You are using bootloaderHID, right? In that case you don't need other hardware, but only the USB connection with the microcontroller. The command should be
avrdude -c usbasp -p atmega128 -U flash:w:myfilename.hex

Good luck.

However, I am unable to burn my project hex file through usb.

I wrote in the command line "avrdude -P com10 -b 19200 -c usbasp -p atmega128 -U flash:w:myfilename.hex"

I used 'usbasp" after -c because this is supposed to be a usbasp emulator, isn't it?

It says programmer not found.

can you help?

I have followed all other protocols mentioned, only that I use Port E as my communication port, and I have an FT232 connected between the USB and the Microcontroller. Would that make a difference?

I have physically connected INT0 to my D+ pin, so I guess that should do?

Hi Matrixstorm,

Sure, you can mark ATmega128 as tested (16MHz) in the next commit to github.

I also give USBasp loader star on github now. You did a wonderful work.

Nice to talk to you, too.

Hi trkien.

I am glad I could help.

Since you sucessfully tested USBaspLoader with ATmega128-16AU, may I mark ATmega128 as tested (16MHz) in the next commit to github?

Btw.: If you like USBaspLoader, please give it a star on github

Hi Maxtrixstorm,

It is my mistake at somewhere in hardware connections. You are totally right with the suggestion fuses.
I checked again and everything works well.

By the way, using INT3 instead of INT0 also works well.

Thank you very much.

trkien.

Hi trkien.

What is the vlatge you are using the ATmega128 on?

Because ATmega128 for 16MHz only runs stable at 4.5 .. 5.5V, the fuses were configured to activate brown out detector.
Without brownout detection, the bootloader section may destroy its contents by itself (brownout during write) and the bootloader will be bricked!!

Also the Value 11 for START-UP TIME is marked as reserved and makes no sense:
Activating the BrownOut with BODLEVEL 4.5V and given the ATmega128 maximum time to start-up: Adjusts your low-fuse (0xbf) into 0x1f.

To your high-fuse:
You are using the value 0xd0, which is pretty much the same than 0xc0: Except CKOPT which is one in your case.
But using a crystal (as it is recommended for VUSB) this Option needs to be zero: HFuse = 0xc0

Please also note, that leaving the lock-bits unchanged at their value 0x3f is important to have all functions of USBasp work properly.
The old way of protecting the bootloader section by programming the proper LOCKBITs is deprecheated now and done in software.

Waiting for your response,
BR matrixstorm

Thank you Matrixstorm,

I can compile and the code works well with Atmega128 now.
However, it cannot work with USBasploader suggestion fuses. It works with my previous fuses: HF:0xd0, LF:0xbf, EX: 0xff.
Anyway, thank you very much.

Hi trkien.

First of all, I recompiled your USBaspLoader configuration:
http://matrixstorm.com/baerwolf/files/t ... rieken.zip
http://matrixstorm.com/baerwolf/files/t ... en.zip.asc

Within the ZIP there is also a patch-file (against current testing-head), which indicates to you my changes for your configuration.
(Please clone a fresh copy before applying patch, since: https://github.com/baerwolf/USBaspLoade ... a3e18df5ed)

However I do not recommend your fuse configuration (YOURS: HF:0xd0, LF:0xbf), since you forgot the efuse and USBaspLoader suggests:
FUSEOPT_128 = -U lfuse:w:0x1f:m -U hfuse:w:0xc0:m -U efuse:w:0xfd:m

Hi matrixstorm,

Happy to hear response from you.

As your comments, I used testing-branch with some modifications:
- bootloaderconfig.h:
#ifndef USB_CFG_IOPORTNAME
#define USB_CFG_IOPORTNAME D
#endif

#ifndef USB_CFG_DMINUS_BIT
#define USB_CFG_DMINUS_BIT 6
#endif

#ifndef USB_CFG_DPLUS_BIT
#define USB_CFG_DPLUS_BIT 0
#endif

#ifndef JUMPER_PORT
#define JUMPER_PORT A
#endif

#ifndef JUMPER_BIT
#define JUMPER_BIT 4
#endif

- Makefile.inc
F_CPU = 16000000
DEVICE = atmega128

- FUSES:
FUSEH = 0xd0
FUSEL = 0xbf

Result: USB Boot still not working. I am sure to connect PA4 to GND ( bootloader condition).
Can you send me your compile project with atmega128 including hex file?
I am looking for your reply.

Thank you very much.
trkien.

Hi, it's again me:

If you want to try the new, revised USBaspLoader please use the testing-branch (https://github.com/baerwolf/USBaspLoader/tree/testing).

From the previous message motivated I tried to compile and experienced an build-issue for ATmega128.
I fixed the Bug and commited it to testing-branch.
