Hello,

I'm trying to restore an SB70LC to the factory application. The project "examples/SB70LC/SB70LCApp" is not the same application (different web pages, options, and behavior). Is the factory application available somewhere?

Thanks,

Joe

Hi Joe,

The factory images for most of the products are on the resources page. Here's a link: http://www.netburner.com/resources/
If you want to use that application as an example and build it, you need the ssl software.

Thanks. I didn't know that. I thought every development kit included the source for the factory application.

Maybe you can help me with another question. The factory app in the SBL2E evaluation kit is a 2-port ethernet-to-serial converter. In my testing, with a loopback connector on both of the 232 connectors, the throughput is for that application is 80-90 packets per second per serial port. With the SB70LC factory app and the MOD5234 factory app (with approximately the same configuration), the throughput is about 5 packets per second per serial port. Is the source for the SBL2E factory app available to use as a starting point, and do you know why the others are so much slower?

I think thats true, but the ssl factory example comes with the ssl software.

No idea there. But I would check with their support directly. There is no reason the platforms should not be able to get the same speeds, in fact, I would expect the SB70LC and MOD5234 to be faster since the processors are faster, but maybe I'm missing something. Also, saying "packet" could be misleading because a packet can contain any number of bytes of data. A lot can depend on the application as well. If you want to test that way you should write a simple program on those other platforms that just does your loopback and go from there. I do know the network stacks are different for the SBL2e vs. anything else, so the code example might not be that useful.

Thanks again. I've got loopback connectors on the 232 ports, so the test can use the factory apps. I use a test application on the PC that connects via TCP and sends packets with a configurable number of bytes. The numbers I quoted were for 32 bytes of data per packet. The SBL2E application does process fewer packets as they get longer. The SB70LC will eventually get a little slower than 5 per second if the packets are very large.

What baud rate are you running at for the serial ports?
