My Atsamd11c14a¶

In this documentation, I will go through my failures and success storys of ATSAMD11C14A.

So What is ATSAMD11C14A

It is an ARM based microcontroller, which comes under the series of M0+ Cortex
It is one of the new microcontroller, which have more advantages that AVR chips
It requires single boot with programmer, and rest of the flash can be done only with microcontroller there is no requirement of programmer
It has more flash memory to store your programe
It follows only Jtag (Joint Test Action Group) and SWD (Single Wire Debugger) protocols for debugging and uploading bootloader
It required initial bootloader or firmware to kick-start the SAMD, where it is not necessary in ESP32

S0, Now we will see.. what are the ways, we can upload bootloader to ATSAMD11C14A chip..

With help of Atmel-ice and Arduino IDE(easy but expensive to buy Atmel-ice)
With help of Atmel-ice and Atmel Studio(expensive to buy Atmel-ice, need to learn about atmel studio, and need to buy atmel software to use atmel studio)
With help of Jlink-Segger and Arduino IDE(easy but expensive to buy Atmel-ice)
With Open Source Debugger know as OpenOCDand raspiberry pi is used as system or Interface(Simple way for the raspi users)
With EDBG and Praticle as Interface in any Operating System

Test - 1¶

For test-1, I have designed a ATSAMD11C14 like this..

This board look similar to FAB-SAMD Board, which also know as Hello.CMSIS-DAP.. If you want to see FAB-SAMD(click Here)

Here is My Schematic of SAMD11C14A..

This is Current condition of MASK_SAMD-CMSIS_DAP

Programming the Initial bootloader..¶

I followed last 2 steps only.. that too.. Failed. The Steps are:

With Open Source Debugger know as OpenOCDand raspiberry pi is used as system or Interface(Simple way for the raspi users)
With EDBG and Praticle as Interface in any Operating System

My References for uploading bootloader from Youtube:¶

This is from Adafruit....

This video, I personally, liked the way he documented… and very informative

This video is a docmentation video on atsamd11c14, by Fab Lab ULB

After Reading and Seeing Video..

My failure¶

In this vidoe you can see, I was not able to program ATSAMD11C14A with Raspiberry via OpenOCD. You can notice the error indicating, while excuting the code..

After, mind bloggings trouble-shoots, I made a issue in a github with the edbg, creater ataradov.

Hence, this helped me to resolve the issue. Moreover, I also got an piece of information,

EDBG is completely compatable with “Windows” & “Linux” as they update their USB drivers, but in the case of “Mac” they don’t update their USB driver, Hence due to that I was not able to excute EDBG to my ATsamd11c14a IC.

After, Resolving it I got an output like this..
