Hi,
I'm implementing the app which part is handling IR remote control. The only thing I need to do is to handle IR codes by ESP32 from remote control.
I used IRremote libary because it seemed to me the easiest way. It was, until it occured that I need to implement OTA flashing. Then I faced following problem:
So I googled and read a lot of topics on this error. From what I understand, my problem is that there in an interrupt handling and the functions and data are not in IRAM/DRAM....Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory region accessed)

What I did then, was to add IRAM_ATTR and DRAM_ATTR to my code related to IRremote
Code: Select all
IRrecv IRAM_ATTR irrecv(IRRECV_PIN);
decode_results DRAM_ATTR results;
unsigned long DRAM_ATTR receivedIrCode;
void IRAM_ATTR handleIrCode() {
if (irrecv.decode(&results)) {
switch (results.value) {
case 0xFF629D:
case 0xFFA857:
case 0xFF02FD:
case 0xFF6897:
case 0xFF9867:
case 0xFFB04F:
case 0xFF18E7:
case 0xFF42BD:
case 0xFF52AD:
receivedIrCode = results.value;
break;
default:
break;
}
irrecv.resume();
}
}[ ] Place transmitting functions of SPI master into IRAM
[ ] Place SPI master ISR function into IRAM
[ ] Place transmitting functions of SPI slave into IRAM
[ ] Place SPI slave ISR function into IRAM
So, the next error while OTA flashing I got, was not in my code but in the IRremote lib rather.
So I tried to add IRAM_ATTR and DRAM_ATTR to functions and variables in the lib and remove errors one by one but eventually I gave up on the error:
I'm not sure but I think, that’s not the way I should proceed. To be honest I don't have any ideas how to move further......

I don't care about interrupts while OTA flashing so they can be disabled.
Could you please help me to find a solution? I'd like to mention that I do have also added LCD TFT SPI (ILI9341) support in my app, which also may cause the problem but I didn't see any direct symptoms yet.
thank you in advance,
Wojtek
