Problem Using Examples from AmbiqSDK 2.2.0 with Artemis RedBoard

Development Boards Artemis
1

I am currently using this Artemis RedBoard: https://www.sparkfun.com/products/15444.

I am also suing the following example from Ambiq SDK 2.2.0:

AmbiqSuite-Rel2.2.0\boards\apollo3_evb\examples\ble_freertos_amdtpc\gcc

I have added the following target to the provided Makefile for that example:

boot_artemis: wired_update

python3 …/…/…/…/…/tools/apollo3_scripts/ambiq_bin2board.py --bin $(CONFIG)/$(TARGET).bin \

–load-address-blob 0x20000 --magic-num 0xCB -o ${TARGET} \

–version 0x0 --load-address-wired 0x0C000 -i 6 --options 0x1 \

-b 115200 -port ${SERIAL_PORT} -r 2 -v

I can build and upload the code to the Artemis RedBoard using the git bash and above target with no error as seen below:

$ make boot_artemis

…/…/…/…/…/tools/apollo3_scripts/create_cust_image_blob.py --bin bin/ble_freertos_amdtpc.bin --load-address 0x10000 --magic-num 0xCB -o bin/main_nonsecure_ota --version 0x0

Upload complete!

However, uploaded example is not producing any output and I am not sure if it is running or not.

I have also tried the load address of 0x10000 instead of 0x0C000 with no effect.

This example runs fine on the Edge board but not on the Artemis RedBoard.

is your makefile using the proper bsp?

does that example use any pins as buttons / inputs that may stop or change the program execution?

liquid.soulder, this code is one of the standard examples that is provided in Ambiq Apollo3 Blue SDK Rel 2.2.0 (Ambiq Micro Apollo3 Blue SDK Rel2.2.0).

This example resides under the following path in AmbiqSuite-Rel2.2.0\boards\apollo3_evb\examples\ble_freertos_amdtpc and runs fine on the Edge board but not on Artemis RedBoard.

This example implements a Bluetooth client and I do not believe that it is using pins as buttons. When it runs, it should present the user with a text based menu on the terminal and expects user to select one of the presented options as a number.

The Makefile that resides under AmbiqSuite-Rel2.2.0\boards\apollo3_evb\examples\ble_freertos_amdtpc/gcc is attached. It is using the bsp library that resides under AmbiqSuite-Rel2.2.0\boards\apollo3_evb\examples\ble_freertos_amdtpc/gcc/bin and I assume this BSP library is for apollo3 that both Edge and Artemis boards are using. If not, I don’t know which bsp from this package is appropriate for the Artemis board.

For some reason, this site does not upload the file (Makefile.zip). A blue progress bar indicates that the file is being uploaded but the file does not show up on this page.

that BSP is mis-matched - it is for the Apollo3 Evaluation Board (EVB). You can find BSPs for SparkFun boards here:

https://github.com/sparkfun/SparkFun_Ap … Suite_BSPs

or integrated with the AmbiqSuite SDK here:

https://github.com/sparkfun/AmbiqSuiteSDK

however I don’t think that is exactly the problem.

I have also experienced this sort of issue and believe the solution involved carefully reading through the code and printf debugging

Thanks for your help. I will give it a try.
