Would you please explain your scenario in details with statistical data as well? Also, Would you please try with direct file instead of creating file inside directory? Because there might be chances of getting delay while writing data into file system? Also are you using standard SPIFFS or loboris ...

Would you please check without using PSRAM 4MB to bifercate issue like it is due to PSRAM or something else? So that it will be helpful to debug further as per analysis or traces into deep level. Thanks. Totally cut out PSRAM from my system is somehow difficult as the data complexity in the system ...

I occasionally ran into panic as listed below: Guru Meditation Error: Core 1 panic'ed (Interrupt wdt timeout on CPU1) Core 1 register dump: PC : 0x4011c576 PS : 0x00060f34 A0 : 0x800d8c09 A1 : 0x3ffd1150 0x4011c576: DPORT_REG_READ at /Users/gl/esp/esp-idf/components/esp32/hwcrypto/aes.c:343 (inlined...

Thanks for the hint. I tried increasing page size from 256 to 1024 which did no help. Worse, it's performance downgraded by ~50%. I also tried increasing block size from 4096 to 8192 or 32768, but they won't work (complained NOT A FS error). However, by reduce partition size to 4MB I can see more th...

Thanks loboris for the reply. Any clue to the cause?

Hi, I found fopen/fread spiffs files on my board are extraordinary slow. The board I have is an ESP32-WROVER-B board with 16MB spi flash. About 10M of the flash is partitioned as spiffs. On the spiffs, there are several files arranged in at most two level sub directories. Sizes of the files range fr...

Thanks. It works now.

Hi, I was reading zero byte for files created using mkspiffs ( https://github.com/igrr/mkspiffs.git ) How I make the file system image mkspiffs -d 5 -c res/ -b 4096 -p 256 -s 0xF0000 spiffs.bin How I flash it python esptool.py --chip esp32 --baud 912600 write_flash -z 0x210000 spiffs.bin How are the...

Indeed, there is one simple wraper function missing IRAM decorator actually called by my ISR. Thus cause the panic. Though, it works pretty well on my 4MB board.

Thank you sir, igrr, for help me find it out.

Hi, I have an ESP32-WROVER-B module with 16MB flash partitioned as follows: nvs, data, nvs, 0x9000, 0x4000, otadata, data, ota, 0xd000, 0x2000, phy_init, data, phy, 0xf000, 0x1000, factory, 0, 0, 0x10000, 2M, ota_0, 0, ota_0, 0x210000, 2M, ota_1, 0, ota_1, 0x410000, 2M, storage, data, spiffs, 0x6100...
