Firmware Updater stuck on "Synch with programmer" #5

Open PKGeorgiev opened 8 years ago

PKGeorgiev commented 8 years ago

I'm trying to add new certificate to my mlk1000. My steps were:

1) I've uploaded FirmwareUpdater sketch to the MCU with no errors 2) I ran winc1500-uploader.exe -address=*****.com:443 -port=COM4 3) The result is:

2016/05/03 17:45:31 Connecting to programmer 2016/05/03 17:45:33 Synch with programmer

The same happens with winc1500-uploader-gui. It stucks on "Synchronizing with the programmer".

My configuration: 1) IDE selection

2) OS Windows 10 3) Genuino MKR1000, MR510PB 4) CheckWifi101FirmwareVersion returns:

WiFi101 firmware check.

WiFi101 shield: DETECTED Firmware version installed: 19.4.4 Firmware version required : 19.4.4

Check result: PASSED

5) WiFi 101 version 0.9.1 6) Board Library: Arduino SAMD boards version 1.6.5

UPDATE: after trying to unsuccessfully update certificates on my MKR1000, it will not handle SSL connections at all. I've tried WiFiSSLClient sketch and it fails to connect to google on port 443. The output is:

Attempting to connect to SSID: Connected to wifi SSID: IP Address: 192.168.43.18 signal strength (RSSI):-39 dBm

Starting connection to server...

disconnecting from server.

The normal WiFiClient sketch works.

Interestingly, after soldering the two racks /male strip headers/ (for testing gpio pins) - I was able to upload custom certificates. May be the problem was due to some "noise" or something. If somebody encounters the same problem - just solder the racks and try again.

p.s. I haven't tried lower baud rates. May be 115200 bps is too high and make the connection unstable?

Could you please expand on what this mean?

Since the MKR1000 uses native USB for the Serial port, the baud rate is not actually used.

@sandeepmistry after soldering the two male strip headers to the MCU I was able to upload certificates to mkr1000 without problems. My theory is that sometimes there may be some interference at 115200 bps. I cannot prove it, because I have only one MKR1000 at the moment. I've seen other people experiencing the same problem.

@PKGeorgiev there's most likely something software related. The h/w pins are not used for the USB data transfer for firmware upload.

I've seen other people experiencing the same problem.

Where have these been reported?

I know there is an open issue with OS X and firmware updates over native USB ports (which something like https://github.com/arduino/ArduinoCore-samd/pull/116 resolves).

@sandeepmistry , my OS is Windows 10. I've found some comments like http://mohanp.com/mkr1000-azure-iot-hub-how-to/#div-comment-37

It is fact that I wasn't able to upload certificates without first soldering the two male strip headers to the MCU. That's why I suggested more verbose output in the CLI.
