软件:相同的程序(仅仅为了适配两个板,led的io不一样)
硬件:两个板,一个开发板,一个自己做的板。核心元器件是一样
问题:开发板每次插拔电源都能正常启动。自己做的板,插拔电源时,概率性程序没有正常运行,有时候通过复位可以正常运行,有时不行
Hi @ccc_clive ,
Thanks for your interest in NXP I.MXRT series.
Would you please help to check the power-up sequence with your board? Make sure that the power-up sequence matches the requirements in the data-sheet.
In particular, it is recommended to try increasing the value of 0.2xRC to ensure that DCDC_IN reaches 3V.
Best regards,
Gavin
