Thanks for your report. I created a fix for it. It will be merged soon. You can use this patch to resolve this issue.

Hi Malishev.

Thank you for your report about it. We have fixed this recently - https://github.com/espressif/esp-idf/co ... 3dbc2d066b.
This fix disables interrupts up to 5 levels for two DPORT workarounds. (will merge it as well to 3.3, 3.2 and 3.1).

I tried so and it works for me: typedef struct { uint8_t crc; uint8_t macAddr[6]; uint8_t reserved[16]; uint8_t version; } ESP_FUSE3; rc = esp_efuse_read_block(EFUSE_BLK3, &fuse3, 0, sizeof(fuse3)*8); Propably I was wrong when suggest that size = sizeof(fuse3), need to use sizeof(fuse3) * 8 (due to ...

Hi mzimmers! 1. Your ESP_FUSE3 fuse3 is: struct ESP_FUSE3 { uint8_t crc; uint8_t macAddr[6]; uint8_t reserved[8]; uint8_t version; }; This structure is 8+8*6+8+8 = 72 bits. But in your code you do `rc = esp_efuse_read_block(EFUSE_BLK3, &fuse3, 0, 192);`. You have to use your real size of fuse3. The ...

Hi, dhananjay.sutariya. When you download your firmware first time, OTADATA will be erased. In bootloader, it set to the right ota_seq and ESP_OTA_IMG_VALID state. It means that in an application your code will be not checked by the diagnostic code, because you have only one bootable app and rollbac...
