Hi i am working on ESP32
while using uart-1 receive interrupt and WiFi together in ESP32 , module is resetting after receiving data 3-4 times, the same functionality is working fine with uart-2 , can anyone suggest solution to fix this issue.
here i am attaching the code what i am using please find the attachment below.
Thanks & Regards

Pin 9 and 10 are used for the SPI flash as well; putting an UART there interferes with reading code from that flash, making everything crash. Use different GPIOs and you should be fine.

Thanks for the replay "ESP_Sprite"
I couldn't find any alternative pins for uart1, in datasheet they given only pin 9&10.
I am getting this issue only when WiFi init is called, without that i am not getting this resetting problem.
Could you please check that also,
Now we are in a situation that we cant change the pins of uart1, Is there any alternative without changing the pins to solve this issue.
Thanks

Erm, what do you think the uart_set_pin function is for? You can essentially set the UART pins to any ESP32 pins that way (given they match the characteristics you need, that is, you can't set TxD to a non-output GPIO).
As you have it now, you're essentially pulling up and down the write protect and hold lines of your flash during UART transmissions. As far as I know, there's no simple workaround for that crashing the system eventually.

Hi, one solution would be to execute from ram, instead of flash. And do not use the flash at all...
Sorry to hear about this.
Is this on the D2WD chip?

thanks for the reply
how to use only ram instead of flash , can you please tell briefly or any docs related to that, please share it
Thanks & Regards

I am not an expert in that. Please open a new thread, asking about how to link and execute everything from ram.
