STM32MP157A-DK1的电源适配器怎么选？有推荐的吗？
那都不是事儿 提问时间: 2023-07-25 07:18:52 / 未解决| 我手上的DK1开发板老是提示电源有问题，串口输出提示如下，然后停住了，红色指示灯一直闪烁。USB TYPE-C connection应该没有问题，因为可以连接STM32CubeProgrammer下载更新。我的手机快充支持44瓦。但也不行，我看这个应该是要求5V/3A，不知道哪个适配器/充电器支持？ NOTICE: CPU: STM32MP157AAC Rev.B NOTICE: Model: STMicroelectronics STM32MP157A-DK1 Discovery Board NOTICE: Board: MB1272 Var1.0 Rev.C-01 INFO: Reset reason (0x14): INFO: Pad Reset from NRST INFO: PMIC version = 0x10 INFO: Using SDMMC INFO: Instance 1 INFO: Boot used partition fsbl1 NOTICE: BL2: v2.2-r2.0(debug):v2.2-dirty NOTICE: BL2: Built : 13:36:23, Oct 22 2019 INFO: Using crypto library 'stm32_crypto_lib' INFO: BL2: Doing platform setup INFO: RAM: DDR3-DDR3L 16bits 533000Khz INFO: Memory size = 0x20000000 (512 MB) INFO: BL2 runs SP_MIN setup INFO: BL2: Loading image id 4 INFO: Loading image id=4 at address 0x2ffeb000 INFO: Image id=4 loaded: 0x2ffeb000 - 0x2ffff000 INFO: BL2: Loading image id 5 INFO: Loading image id=5 at address 0xc0100000 INFO: STM32 Image size : 902542 INFO: Image id=5 loaded: 0xc0100000 - 0xc01dc58e WARNING: Skip signature check (header option) NOTICE: ROTPK is not deployed on platform.

有没有可能修改uboot，重编译以后更新可以跳过？

换过，没用。我的手机充电器只支持5V/2A、9V/2A、10V/4A，没有5V/3A,看开发板原理图是把CC1、CC2引入了STM32MP157的

软件跳过检查当然可以。实际上我从电脑USB口取电都能起的来，根据type-c标准上拉CC就是。最简单还是试试换其他线材，不过最好还是找到5V大于3A的适配器。
