Re: Problems with EFFS

I will try some file reading tests to try and reproduce.

Re: Problems with EFFS

Hello, Looking at trying something simple on this end to reproduce the issue. Do you think this would cause the same behavior on your design: - Have four 1MB files on the sdcard - Open each one at at time,read and print some number of bytes larger than 3k, lets say 10k, close the file - Repeat At on...

Re: tls 1.2 vs 1.3

Something else I have noticed on my system. With BitDefender installed, it does it's own certificate check, and I see a bit defender cert, not just the netburner autogenerated cert. Looking into it now, but I think actually goes out and does it's own check in it's cloud database check, which takes m...

Re: tls 1.2 vs 1.3

Hello,

After further testing, we have noticed the speed has decreased from release 3.3.8 to 3.3.9, as the new wolfSSL version 5.5 have different optimizations. We are working on a 3.4.0 release for mid to late March.

Re: tls 1.2 vs 1.3

Hello,

What key size are you using?

As previously mentioned, we have identified a speed issue with 3.3.9 and tls 1.3. Can you confirm the numbers you are now providing are for tls 1.2 and tls 1.3 is not enabled?

Re: Problems with EFFS

Hello, Thanks for posting your app, but there is a bit more going on there than I can sort through. I have not seen this behavior before. As a hardware test, how about the simplest possible program that only reads from the file system? That would be a good hardware reliability test. Put a 1M file on...

Re: tls 1.2 vs 1.3

Hello, 1.2MB is a pretty hefty web page for an embedded device. What is the total used by images? What are you using for the certificate? RSA is very slow, ECC much faster. We have noticed a slow down in tls 1.3 with the latest wolf upgrade that is in 3.3.9. We are looking into that, but it will tak...

Re: CAN-FD

Hello,

Our CAN library does not support CAN-FD. However, the processor is certainly capable.

Re: Problems with EFFS

Hello,

Is this an app that can be run on a development board so we can try to re-create it here? If possible, the simplest code set that demonstrates the issue. Also, it would still help to know your h/w and s/w tools version.

Re: tls 1.2 vs 1.3

Something seems wrong there. Try the unmodified ssl web demo example, then compare the differences to your code. Also, make sure you are in release mode, debug mode will be very slow since it can't use fast ram. Can you verify you are in release mode? What are your reload times for the ssl web demo?...
