Question

How to? I am the newer to the realtek8195AM. After following the installation of mbed-os on realtek8195AM and burn the WiFi example, I use the screen to monitor the board. I found that my board seems to stock on certain point. I can't figure out what happened to it.

Can you try any other example like blinky? https://github.com/ARMmbed/mbed-os-example-blinky please note that the board does not have an user LED so you must add external one or simply add printf in the loop and watch serial.

YiChunHung commented 7 years ago

I did try the blinky example with adding printf in the loop. It does not work. It got stuck at the same point.

Try updating the firmware: https://www.amebaiot.com/en/change-dap-firmware/

YiChunHung commented 7 years ago

I just update the firmware two days ago from the website you post. I update the one name "DAP_FW_MBED_RTL8195AM_V0" and I all follow the steps described in the web. I will try it again later, but I don't think it would work.

@Archcady @tung7970 any ideas guys?

tung7970 commented 7 years ago

The blinky example should have worked. That's the basic HAL thing.

@YiChunHung can you paste the following details

  1. mbedls output
  2. blinky build command

The latest DAPLink support for RTL8195AM is currently under review. https://github.com/mbedmicro/DAPLink/pull/289

You can build one if you have the proper tool.

YiChunHung commented 7 years ago

OK, I will try the latest one, and do some testing. If not working, I will paste the information here. Thanks for your help.

@tung7970 @bulislaw Thanks for helping. I solved the problem. Online compiler seems not to work. I used mbed-cli to compile the program and burn it to the board, it worked totally fine!! By the way, I still pose the information I got. Probably it can help online compiler improve somehow.

  1. mbedls output:

  2. Blinky build command

mbed compile -t GCC_ARM -m REALTEK_RTL8195AM Here is the result

Here is my compiler version

arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors 6-2017-q2-update) 6.3.1 20170620 (release) [ARM/embedded-6-branch revision 249437]

And I didn't change the firmware to the latest one.
