We encountered an issue when we test boot from nand flash and run in sram. 
After download the firmware through USB using MfgTools.exe, keep the power on, every time we press RESET key to reset i.mxrt1050, firmware always boot from nand flash and run in sram successfully. 
But, firmware always fails to boot from nand flash after power cycle, and seems device turn into serial download mode.
