I have bricked Linkit 7688 duo

Anonymous · July 4, 2019, 8:06pm

I have bricked Linkit 7688 duo , not able to flash anything Always gives avrdude content mismatch error. I already posted my problem on YouTube and also on seeds tech support. But no response.

Kindly help, i tried all solution. Reflashing bootloader with usbasp and also with Atmel ICE. But same error

I am waiting for reply

Hi there~,

Please follow Updating Arduino Bootloader to fix the avr chip bootloader issue.

https://docs.labs.mediatek.com/resource/linkit-smart-7688/en/tutorials/linkit-smart-7688-duo/linkit-smart-7688-duo-development-board-and-arduino-ide/updating-arduino-bootloader

If the issue is not solved, Please post the avrdude content mismatch error in text format.

Thanks

Hi Seeed_support
I told, i already followed this guide to flash bootloader from internal
linux.
But there also flashing occurs good getting verification error .

My atmega32u4 fuse setting is
FF D8 CE and lock bit some time 3F sometime FF

What is the reason for verification error.

Please explain me

Hi
I tried but not good luck. Even I selected Leonardo board in Arduino didn’t
work. Then I modified board file of linkit Arduino package. And changed
*extended_*fuses to CB from CE, but didn’t work.
Tried flashing basic blink code getting always this error

[image: image.png]

then even I tried flashing bootloader with Arduino other tools like USBASP
and atmel ICE.
same content mismatch error comes always. I am not understanding why
suddenly got brick and now what is reason of mismatch. Please can you
explain.

Hi

Suman,

We tested with below hardware connection and software configuration. It works with blinking code.

Hi

Suman~

1. Please follow my hardware connection and software configuration to burn the bootloader.

2. If you can not solve it, please provide the detail step by step process, appreciate if you could include the pictures about the hardware connection, as well as your software configuration. So we can help solve the issue.

Program fuse is 0XCED8FF.

In hardware connection i can see only five wires. You are using USBASP i
guess. Is it without reset wire ?

And fuse setting what you sent is a default one only ?

Please can you send me same Progisp software version. And can i use with

1. Please can you send me same Progisp software version. And can i use with USBASP?

It is USB ICSP. Please see attached software.

2. In hardware connection i can see only five wires. You are using USBASP iguess. Is it without reset wire ?

We power it through USB and do not add the VCC pin.

3. And fuse setting what you sent is a default one only ?

We use the software to read it from duo and it is

0XCED8FF.

I am waiting for your response.
Is this your support. You people are not giving clear explanation for the
solution.

Here i am posting complete log of USBASP, please if you people really want
to help then guide me properly. With your product i am stuck now.

Hi

Suman~

1. From the log, we can see the

warning

as below.

-----------------------------------------------------------------

avrdude.exe: warning: cannot set sck period. please check for usbasp
firmware update.

-----------------------------------------------------------------

You can follow below link to update your USBASP to solve the warning

https://tosiek.pl/usbasp-v2-0-warning-cannot-set-sck-period/

or if you have arduino boards, you can follow https://www.arduino.cc/en/Tutorial/ArduinoISP to burn the firmware.

2. If you still can not solve, I am afraid that we can not solve the issue remotely. I will pass to sales team and see if it is in warranty.

Thanks

With the same USBASP i used to burm bootloader on other avr controllers and
its working good.
But i tried with Arduino as ISP method also, here I am attaching log.

Error while burning bootloader.

I think board has some other issue. Kindly initiate my replacement. I
purchased from FabtoLab. I had attached the invoice.
