hello, Eric

If you do all clear with the steps on the web page, could you capture the error message or the problem?

Below url is the way how to use this.
http://wizwiki.net/wiki/doku.php?id=products:wizwiki_w7500:start_getting_started:write_firmware:isp

Please concern

  1. upply power once while pressing the SW2,BOOT switch.

  2. Before click the open button of ISP tool, we suggest you to test it in other terminal windows.
    After opening serial port using the terminal windows,enter the capital “U”. If it is in the ISP mode, you can see the returned character.

thank you

hello,

When I did ISP tool, it works well and download binary file.

I type something you could miss

First, Have to check TX, RX with USB converter and WIZwiki-W7500.

even you check Serial complete message, you have to check serial communication. But as you said, you did it well… so pass!

may you see this one. type the ‘U’ in serial terminal

Second, you must check board is on boot mode. after supply power, release the boot botton. make sure.

Third, it is WIZwiki-W7500.

other things do not make it happen…

If you are all clear… could you let me the all process you did ??

thank you

hello, Eric

Thank you for your capturing.

In ISP download, the baudrate is fixed as 115200

(see this page,
http://wizwiki.net/wiki/lib/exe/fetch.php?w=800&tok=63cabc&media=products:wizwiki_w7500:getting_started:isp.png)

Baudrate does not affect serial open, may the pc uart2usb driver has problem.

Could you re-install the pc uart2usb driver and try again?

The ISP tool must communicate with 115200 baudrate.

thank you

Hello!
I have almost the same problem with WIZwiki-W7500P under Win10 x64:

  1. I can open serial port only with 460800 baud rate
  2. I can not write anything into the flash pushing ISP start button.
  3. Reinstalling drivers provided by mbed (version 2.0.2.0 24.08.2009) does not fix the problem.

Although I had successfuly connected this board on another PC

Also there is another problem which i can not fix:
Even after successful loading of the new firmware into the WIZwiki-W7500P through the CMSIS-DAP onboard debugger, after power on reset it does not start to work! Like if there were no any firmware. Moreover after power on reset the D7 red led flashes very quickly like if LPC was trying to load some firmware into the W7500P, and after 15-20 seconds D7 is turned off and that is all. Nothing happens then. The W7500P does not work how it worked immediately after loading of the new firmware!
Please could you explain me what could be wrong with the serial communication and what else i should do to save firmware in the flash of the W7500P even after power on reset?
