目前采用I.MXRT1020跨界的MCU,使用官方标准的SDK软件包,基于SDK_2.6.1_EVK-MIMXRT1020的IAR 工程中的flexspi_nor_polling_transfer例子进行测试。 官方采用的是ISSI的QSPI NorFlash ISSI IS25LP064A-JBLE,这里更换为 Winbond的W25Q32。通常QSPI闪存大部分是兼容相同的,只需要关心QE位的设置,如果这个位设置不对的...
What version of TLS is in the mbedTLS version that comes with the latest MCUXpresso SDK (in my case for RT1020/RT1050) please? Is it always the latest mbedTLS provided by ARM, e.g. currently TLS 1.2? Thanks. Tags: mbedtls version ...

虽然作为已经量产很久的RT1050/RT1020,它的ROM不可能后面再加上去这套API了,但是NXP虽然关上了一道门却敞开了一扇窗,在RT1050/RT1020的SDK软件包里实际上是包含了这套统一SPI Flash操作的API源码的(\boards\evkbimxrt1050\bootloader_examples\flashloader),这套源码很庞大,包含了UART/USB通信以及SD卡/eMMC/SPI...
NXP SDK software requires 24 MHz on XTALI/XTALO. The crystal can be eliminated if an external 24 MHz oscillator is available in the system. In this case, XTALO must be directly driven by the external oscillator and XTALI mounted with 18 pF capacitor. The logic level of this forcing clock ...

我们知道i.MXRT1060-EVK上默认连的是ISSI的8MB QSPI Flash,SDK XIP工程里默认使用了它的配置,在 \SDK_2.x.x_EVK-MIMXRT1060\boards\evkmimxrt1060\xip\evkmimxrt1060_flexspi_nor_config.c中定义了常量 qspiflash_config,我们可以参考这个常量定义。
