I supposed so but I was considering whether this operation is not negligible.
I'm going to do some about it. My question comes because I have a random delay in phase controls under timer interrupt ne ...

Hello,
Checking assembler generated from CCS V5.077 I realized CCS routine called "read_eeprom" set and reset global interrupt during eeprom read operation. Generally microchip datasheet d ...

Very interesting Ttelmah.

Thanks

Your help is greatly appreciated. I'm going to work around and test it.

Regards,

I solved getting back and use array of strings without pointer.

Hello,
I tried to use text table in CCS I already use with XC8 compiler. This because my string isn't length fixed. Below example of structure of table. In production firmware I have 5 tables with to ...

yes, two partition is best solution but I haven't space. Bootload is used in production from customers so, in case something gone wrong with boot, they return back board. This isn't a a big problem.

I'm working on test with internal oscillator but issue is quite rare so it can take months or years. About bootloader I'll work around as you suggest. I can introduce a flag in order to check if call ...

Bootloader is based on example code of CCS. After received serial command firmware jump to routine waiting for serial string checking start bit and checksum. This is routine of boot.

void boot &# ...

About eeprom write I have zero crossing signal so, in case it miss for more than 50 ms I stop eeprom write. I'll rise up VBOR to 2,5V. I'll try to understand if this change is possible by firmware so ...

This forum is interesting especially because open my mind in order to consider different scenarios.
so:
Micro are new and now we have 2019 data code. Sometime happens on device working from 3-4 year ...

as I told you I'm trying to understand why an application stop to work. It happens very rarely. The same firmware works on different hardware with the same components. I have performed EMC immunity te ...

Yes, I follow your suggestions and also do some test of oscillator components.

Regards,

Really it's a big project I can't post it. I use same fuses configuration from a long time and happens less than 0,01% of production or less and only in some hardware configuration. After reprogramme ...

In fact to protect configuration registers I must set C0 register so reset bit.

I'm doing some test with application based on PIC18F46K22 where sometimes happens it stop to work and checking devic ...
