MCLoader & XPort

[Joe Rocci]

Does anyone have any experience using Mecanique's MCLoader to bootload a PIC over a network by using a Lantronix Port at the PIC end of the link?

I can get the loader to work fine with a direct serial connection, but MCLoader seems to bail out as soon as I try to load over the network. However, I can get Hyperterminal to communicate with the PIC over the network just fine. Could the problem be that MCLoader doesn't have any tolerance for network delays?

I have tried the combination that you are using, and gave up. I think you are correct in your belief that the timeouts in MCLoader are too short.

Charles,

Thanks for the quick reply!

Do you know of a bootloader combo that WILL work through an Xport over a network? The 'network' will eventually include the internet.

I'm using a PIC18F2620.

Thanks

I know of no bootloader combo that will work over an XPORT. I tried uChip's but that doesn't work because it requires a third wire to trigger it. I suppose that with a little re-coding it might be possible to use it.

When I tried MCLoader, I used a serial -> Ethernet utility to telnet into the XPORT. I'm supposing that is the method you tried as well.

My guess is that the only way to make MCLoader work with this setup would be to disassemble it and modify the timing loops. In an attempt to avoid that mess, I contacted Mecanique and asked if they would be interested in modifying their code, or licensing the source so that I could do it. They said they weren't interested in either one.

Hi,

If size if of less importance you can always consider to write the loader your self in PBP. As long as it is for the 18-series it seems to work.

Jumper,

Actually, I made an inquiry about that very idea on this forum about a week or so ago, but I don't recall getting any suggestions.

If you can point me to an example of how someone else did this, I'd really appreciate it

Thanks Joe
