ADC Continuous read and LittleFS bug (IDFGH-14079) #14893

Open GitHubLionel opened 1 week ago

GitHubLionel commented 1 week ago

Hi I use an ESP32 Dev Module and I use IDF version: v5.1.4-497-gdc859c1e67-dirty (esp v3.0.3 in Eclipse Sloeber). My problem is simple : when I use ADC Continuous read and I try to read/write to my LittleFS partition, I crash my program with the error : Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory region accessed). The debug backtrace doesn't help.

I read lot of things about this problem and try to add : 

#define CONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE 1
#define CONFIG_GDMA_ISR_IRAM_SAFE 1

if sdkconfig.h and soc_caps.h files but we no success. I don't know what to try anymore. Any ideas to try ? Thanks Lionel

Hi @GitHubLionel Please use menuconfig to enable these two configs and try again. The linker won't put the function into IRAM if we define the macro by ourselves.

Hi Kainarx Many thanks for your answer. Problem, I use Eclipse/Sloeber and I don't know how to use menuconfig in this IDE. I will ask Sloeber to know that. Best regards, Lionel
