I think there is a bug in the Htp client

When I try to use it, is runs, but it just dont download anything:

[DBG HTCL 331] Reading headers [DBG HTCL 374] Read header : Server: Apache [DBG HTCL 374] Read header : Location: http://www.xxxx.dk/Prog_LPC1768.bin [INF HTCL 392] Following redirect[0] to [http://www.xxxx.dk/Prog_LPC1768.bin] [DBG HTCL 412] Receiving data [DBG HTCL 461] Retrieving 0 bytes [INF HTCL 464] write 207,0: Location: http://www.xxxx.dk/Prog_LPC1768.bin [INF HTfi 40] write(0,Location: http://www.xxxx.dk/Prog_LPC1768.bin) m_len(268443897), chunk 0 [DBG HTCL 502] Completed HTTP transaction [INF SWup 119] Remove bin files excluding {Prog_01.bin} [INF SWup 282] Updating stored version number.

There is no errorcode, just no data. I have tested the webserver just with a browser, and it gets the file.

Software Update via Ethernet - the mbed application can pull down an updated application binary from a web server and activate that binary. This library works only with the LPC1768, … FOTA, LPC1768, SW Update

Hi Gert,

Let me see if I can help.

[A small suggestion first- surround the "listing" with <<code>> and <</code>> to make it easier to read]

From your report, the thing that caught my eye first is m_len(268443897). What I see on one of my systems is 133724 (which is the size of the binary image to download). 268Mbyte is too large for an mbed module, but I don't know what caused such a large number.

I'm going to spend some of the next hour updating the libraries to the latest mbed, rtos and so on and then see if I can reproduce this extraordinary number. I hope to post a follow up in a while, but in the meantime, you might double-check the bin file on your server to see if it is a more realistic size, or if perhaps it was mangled somehow.

Gert,

I updated all the libraries to the latest (mbed, rtos, ethernet and so forth). In my "test" program, I also removed several extraneous things to simplify it down. I added a link to that test program on the SWUpdate home page, and here's a direct link to that demo as PUB_SWUpdate.

If you give this a go and it still does not work, I'd like to see more detail in the console debug report (which you'll have to turn on debug per the instructions on those pages).
