OTA problem with bootloader and reset

I wish to report a problem that we are currently encountering: we did some tests on 17 waspmotes with Digi 802.15.4 transceiver modules (XBee 802.15.4 PRO S1) by sending and executing firmwares through OTA. All motes could successfully receive the firmware sent from a gateway and save the received firmware into SD card (all motes were configured by the same setting). However, 5 motes got stuck after restarted the new program (by -start_new_program command) and no longer gave response to any furthermore OTA command. The phenomenon is the same as what I reported before in a previous topic "Problem of OTA with the use of SD Functions"
viewtopic.php?f=19&t=7801

The difference is that removing the bottom/top battery does not work for them. Furthermore, all the 5 improperly-working motes have very similar product serial numbers which are something like 3030-0005-xxx while the other 12 working motes have different numbers (3030-0004-xxx or 3030-0008-xxx ). Therefore, I suppose it is due to the bootloader.

Since all the 17 motes were purchased at the same time (mid of August 2011), they are supposed to have the latest version of bootloader (v003) but I do not know why the 5 motes are different.

I have ordered an AVR ISP programmer but the waspmote does not have an individual ISP socket (the UART0 is shared with USB/Xbee). Could anyone give suggestion to sort out this problem?

Furthermore, I was told that all motes manufactured after May 2011 should have the reset function available (it is a hardware implementation). However, I did not find the reset command works for our case, could anyone let me know how to better verify the if the function works or not?

Many thanks!

It would be interesting to see some results of the 17 motes. How much time did it consume? hmmm try the following on the improperly working nodes: -

- Remove SD card, batteries

- Format SD card to fat16 with gparted

- Try them one by one.

- If you get message program receive error. try initializing SD card in main setup() and try again and then remove the initializing and see if that makes any different.

Dear AmroQuandour, thanks again for your kindly advice. I formatted the SD using gparted, unfortunately it did not make any difference. Now I am trying to find a way to re-load the bootloader. Any suggestion?

Hi,

Are you able to upload codes with the Waspmote IDE?
How big is the code you are trying to update through OTA programming?

The reset function should work with out problems. Anyway, you can send us a picture of the front side of Waspmote in order I assure you are able to do reset functions.

Regards

Dear libelium-dev,

do you have any Email address? I can send the picture to you. Besides, is there any way we can re-load the bootloader?

Hello,

You can use a free service like image shack. The image should not be bigger than 600x400.

We have seen you have opened a new thread for the same OTA questions. Please donnot duplicate the posts.

Best regards

Dear libelium-dev, thanks for your reply. I will upload a pic via a server.

Besides, I did not duplicate any post. The new post has nothing to do with this topic. Could you please give any suggestion for the new problem? Any help will be much appreciated!
