SDK v1.4.0 Release Notes

Since the release of version v1.3.0, we have made improvements and optimizations in several areas of the application. These changes are divided into two main sections: Major Changes and Changelogs. Here, we’ll provide a detailed explanation and enhanced descriptions.

Major Changes

In this update, we have made significant optimizations and upgrades to the core modules of the system to enhance performance, add new features, and improve user experience. The changes are primarily categorized into Major Features, Major Bug Fixes, and Breaking Changes. Here are some of the key updates:

• Major Features

  • Add get_ic_euid() API. (9aedebe2)

  • Add pm_cpu_freq_get() API. (b96da884)

  • Add fmc_flash_set_4_byte_address_mode() API. (fde60dfc)

  • Add fmc_flash_set_default_bp_lv() API. (2921dba1)

  • Add I2C I2C_INT_MST_ON_HOLD interrupt bit and some flags. (01068ea7)

  • Add SPI0 high-speed function SPI0_HS. (9bdca02f)

• Major Bug Fixes

  • Fix realloc error when using FreeRTOS. (9aedebe21)

  • Fix bug of le_get_conn_local_addr(). (196283)

  • Fix dfu_checksum error when image size is above 8MB. (0dc44bf4)

  • Fix LPC config threshold error. (5fef0179)

    • RCC_ENHTIMClkConfig is renamed as ENHTIM_ClkConfig().

    • RCC_I2CClkDivConfig is renamed as I2C_ClkDivConfig().

    • RCC_IRClkConfig is renamed as IR_ClkConfig().

    • RCC_SPIClkDivConfig is renamed as SPI_ClkDivConfig().

    • RCC_SPIClkConfig is renamed as SPI_ClkConfig().

    • RCC_TIMClkConfig is renamed as TIM_ClkConfig().

    • RCC_UARTClkDivConfig is renamed as UART_ClkDivConfig().
