Teraterm - no activity in the window.

[point38]

I'm trying to figure out why I don't see the output from my FRDM-KL46Z dev board in Teraterm.

Installed the latest serial driver and updated the firmware of my dev board to latest as well. Successfully uploaded a few demo programs to my dev board - they work as expected. Under the Portable Devices in Device Manager I can see MBED listed. I use correct settings for Com communication but when I connect the screen is blank with no activity.

Ok, I figured what went wrong. I uninstalled nxp's mbed driver from devices and hardware under USB and re-installed it. It started to work and now I'm able to see mbed Serial Port in TeraTerm! Your screenshot gave me a hint, so thank you!

Hi

Have you tried to download FRDM-KL46Z Quick Start Package? This quick start package provides the OpenSDA image(MSD-FRDM-KL46Z48M_Pemicro_v113.SDA) for FRDM-KL46Z. After the board be updated with this OpenSDA image, customer could find the USB CDC virtual serial at Computer management panel. Then there should with serial print info when customer drag the pre-compiled example, such as [low_power_demo_freedom.srec] to MSD disk named <FRDM-KL46Z> . Then with below serial terminal setting, there should with serial terminal print info.

Wish it helps.

Have a great day,
Ma Hui

Hi Ma Hui,

unfortunately, I already tried this approach and it's not the latest firmware.

Here Firmware FRDM KL46Z - Handbook | mbed  you can find the latest driver and a firmware. I don't see a way of how this can be fixed, there must be an issue with a firmware but if you have Win7 then you can try installing driver and firmware and let me know if you had any luck with Teraterm of similar.

Thanks

Hi

I had tried the below MBED image and could get the serial terminal print info:

Below is my Win7 info:

If customer still meet problem with MBED OpenSDA image, I would recommend customer try with Segger J-Link image for OpenSDA. Customer could download related image from here.

FRDM-KL46Z OpenSDA bootloader version is V1.0

Wish it helps.

Have a great day,
Ma Hui

From what I see you simply drag-n-dropped .s19 firmware to bootloader and mbed serial port (83) showed up in HyperTerminal? Looks like it worked for you. I also tried Segger's J-Link and that didn't help. There must be something else going on, that's weird. Thank you for you help anyway!
