Additionally supports ECC608 Integration with FreeRTOS and Wi-Fi Support(WINC1500/WINC3400) for SAM S70, SAM E70, SAM V70/V71, PIC32MZ EF and SAMG55 MCUs.
Supports FreeRTOS’s OTA Firmware Update with WINC1500 and SAME5x, SAMD5x.

The following table provides number of demo application available for different development kits:


Development kits	Applications
SAM E70 Xplained Ultra Evaluation Kit	2
SAM E54 Xplained Pro Evaluation Kit	4
Curiosity PIC32MZ EF 2.0 Development Board	2
SAM G55 Xplained Pro Evaluation Kit	1


Issue Description	Workaround
For SAME70, PIC32MZ and SAMG55, the I2C baud rate generated by cryptoauthlib is inconsistent (has 3 additional zeros) and needs to match with speed configured in the peripheral.	Remove the additional zeros in baud rate configuration of the peripheral in ATECC608_0.c
The SAMG55 FreeRTOS NVIC Priority configuration is incorrect, causing XSemaphoreGiveFromISR to assert.	Set NVIC_SetPriorityGrouping to zero in pblic_nvic.c
After Programming with MPLAB 5.45, data on PKOB based UART in curiosity 2 PIC32MZEF board is not received correctly, so use MPLAB 5.40 for Programming Curiosity 2 board	For Programming Curiosity 2 PIC32MZEF, use MPLAB v5.40

Supports ECC608 Integration with FreeRTOS and Wi-Fi Support (WINC1500/WINC3400) for SAM D5x/E5x MCUs.
Updated version of FreeRTOS 202002.00 to add support for following SAM S70, SAM E70, SAM V70/V71, SAME5x, SAMD5x, PIC32MZ EF families of 32-bit microcontrollers to securely connect to the AWS Cloud.
