Document JLink Debugger Support

//I changed the following changes as I want to check only power-down mode
#define USE_BUTTON 1
#define USE_ALARM  0

#define DISABLE_GPIO 0 //it configures all GPIOs as input to save power

#define DO_SLEEP     0
#define DO_LPM       0
#define DO_UPM       0
#define DO_STANDBY   0
#define DO_BACKUP    0 // will reset after wakeup`
#define DO_POWERDOWN 1 // will reset after wakeup

Now I am using FTHR board,
Red light on > Clicked the trigger button > Red light off > waiting for 3.0/3.1 to be pressed.
I connected the pin 3.1 to the gnd and found nothing is happening ?
It should be supposed to wake up right? not happening. Is something wrong with my expectation?

Examples/MAX78000/LP/main.c
Path of the code

[aniktash]

Please use P3.0 or reset instead of P3.1. In either case, a reset will be triggered.

[chaitanya-smartrotamac]

How to use P3.0 because it is a shared signal between PMIC and MAX 78000 IC.
I am using the FTHR board.
is there a way I can use P3.1?

[aniktash]

Unfortunately not, only P3.0 or reset can be used as the wake-up source in Power Down mode. The example and documentation will be updated soon.
You may use the reset instead, which works the same way.

Thank you @aniktash
We will use P3.0 in our product design.

Next question, this may not be related to the actual question

While I am testing I found
"#include "led.h" "
and
"#include "pb.h" "

in code path : https://github.com/Analog-Devices-MSDK/msdk/blob/main/Examples/MAX78000/LP/main.c

includes paths that are not visible to the Eclipse IDE

• I added the maxim SDK path also.
  

check my includes, I included almost everything. Still there are some red line missing includes.

Did I miss something?

[aniktash]

There seems to be some includes missing compared to the original LP example project. You may want to try to add them, or import the original example:

[chaitanya-smartrotamac]

yes, you are right @aniktash .
But I thought adding just the /MiscDrivers will add all driver-related files.

Still, I can find some includes are missing, Can you tell me what are they?

though they are missing, Still the compiler can see them while building and always has 0 errors.

[aniktash]

This is just to help the Eclipse IDE indexing. They are not needed to build; The compiler uses make files to find them.
LED1 and CONSOLE_UART are in include files:

pb_pin is here:
C:\MaximSDK\Libraries\Boards\MAX78000\EvKit_V1\Source\board.c
Generally, the indexer should be able to find if it is enabled:

Sometimes the indexer needs help; You may need to choose to search for unresolved includes, re-resolve or refresh and rebuild:

"Sometimes the indexer needs help; You may need to choose to search for unresolved includes, re-resolve or refresh and rebuild":

Wow, That rebuild indexing did the trick. Thank you @aniktash

This will be my last question in this post chain,

How to find to which function it was referring?
I tried ctrl+click but it is going nowhere.

When debugging I can see by stepping in, But is there a way to know without debugging?

[aniktash]

The peripheral drivers are in this folder: C:\MaximSDK\Libraries\PeriphDrivers\Source
Inside each peripheral folder, you can find the specific driver for MAX78000 tagged as ai85 (it's our internal die name), e.g.
uart_ai85.c.
For some peripherals, a generic driver is used, or a driver from another die (me17). You can see the list of drivers used for MAX78000 in this make file:
C:\MaximSDK\Libraries\PeriphDrivers\max78000_files.mk

[chaitanya-smartrotamac]

Thank you @aniktash
One more last issue. We developed our custom board with MAX78000 and found that JLINK is officially supported. We tried it with no luck.
Is there a example code or project how to setup the Jlink to program max78000?

[aniktash]

@jessexm could you please support?

[Jake-Carter]

@chaitanya-smartrotamac I have a J-Link setup guide for Visual Studio Code on the VSCode-Maxim wiki here: https://github.com/Analog-Devices-MSDK/VSCode-Maxim/wiki/Segger-J-Link-Setup-Guide

There is an option to use either our OpenOCD server or the native JLink GDB server, which is discussed more in the document.

The setup guide will be migrated to the official MSDK User Guide soon, so if you encounter any issues or any missing info please let me know.

A tip for troubleshooting: If you have issues connecting with a JLink debugger try connecting with our PICO debugger first, and verify that works. If the PICO cannot connect either, then there may be some hardware issues with the custom board.
