Reset Cause

With the MCF54415 processor, on bootup is there a way for an application to distinguish between a power-up condition and a hardware reset by toggling the reset pin? I didn't see anything in the library manual or the MCP54415RM manual, but I may have missed it? The RM manual is over 1300 pages and th...

Re: tls 1.2 vs 1.3

I am unable to recover this MOD5441X module. I short TP1 pads, power-up. Module goes to the Alternate Boot monitor. Using FLA, I upload Mod5441x_FactoryApp.s19 successfully, but when it boots I get message INVALID Csum. I've done this multiple times with the same results. ******Erase FlñBoot record ...

That didn't work so well. -------------------Trap information----------------------------- Stack is corrupt A7= SwapOutA7=00000000 SwapOutTCB=00000000 SwapInA7=00000000 SwapInTCB=00000000 ...

Re: tls 1.2 vs 1.3

I installed v3.4.0 and built my app, and retested loading a webpage using tls 1.2, and the time to load is about the same as in v3.3.9, 35-40 seconds on a MOD54415. I will look at moving to web sockets. That made a big improvement with v2.9.5 of the tools, under 10 seconds.

Re: Secure connections

Testing of the HTTPs_Intercept task above successfully intercepts a secure connection attempt every time (so far), as long as the task is launched after StartHTTPs(), even though the intercept task has a lower priority (usermain-2) than the HTTPS task. I would expect that if two tasks are pending fo...

Re: Secure connections

That would require a major rewrite of the firmware. Not happening any time soon.

Re: Secure connections

Is it plausible to created a new task at a higher priority than the HTTPs task that would detect a connection request, send a notification to the user via the display, then let HTTPs to run? For Example: void HTTPs_Intercept(void * pd) //create task after StartHttps() { static fd_set reader; static ...

Re: Secure connections

The touch screen interface is part of usermain, which has a priority of 56. The touch screen has its own processor and the interface is rs232 at around 400k baud. There is no touch screen task. I assume TCP negotiation is priority 45, but may maybe secure TCP uses priority 43. We don't use WI-FI, PP...

Secure connections

One of our products has a touch screen interface, and when a browser attempts to make a secure connection, the display freezes for 20-30 seconds during the negotiation. Is there a way to minimize that freeze-up so an operator doesn't think the unit has crashed or something? I'm using v2.9.5 with a M...

Using htmlfiles.h

For v2.9.5, file htmlfiles.h has no guard against multiple inclusions. Is this intentional?
