Boot error after upgrade to esp-idf 4.4.3

[afcec1]

Hi, we developed some years ago a product based on ESP32-WROOM_32D, initially using ESP-IDF 4.0.1. It has been working successfully until now. We have initiated a migration process aimed at ESP-IDF 4.4.3 (last stable release). After changing everything related to tcpip_adapter and solving an issue due to a call to adc_gpio_init (now deprecated), I was able to successfully build the project. However, after flashing, the board won´t start and we are receiving the following error:

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

load:0x40078000,len:17668
load:0x40080400,len:3272

Could you please help me?

Thanks

I tried to go step by step so I downgraded to esp-idf 4.1 but it does not work either. The error is the following:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

I will keep on replying to myself

I connected the debug serial port and this is what I see. As far as I understand it seems I am using part of the reserved memory? How is that possible? Does anything change between 4.0.1 and 4.1? By the way, I am using flash encyrption and this is my partition table:

I don't see an actual "error" message in any of those outputs. Is the displayed app version correct? Is that all that is displayed? What happens afterwards? Does the ESP32 just hang, or does it continue rebooting and displaying those same messages? Your partition table appears to be Ok, as far as I can tell. Maybe the encryption is causing an issue in the upgrade (?).

The error is the watcjdog reset itselft, which is happening continuously. Looks like increasing CONFIG_BOOTLOADER_WDT_TIME_MS from 9000 to 12000 did the trick and now the application is starting correctly. Thanks.
