Power Supply for STM32MP157C-DK2

[SChau.2062]

Hello,

We would like to setup the STM32MP157C-DK2 board. But we couldn't find any information related to the recommended power supply.

Could you please suggest us that which Power Supply 5V/3A adapter or connector should we use? It would be great if you can provide us link to purchase the power supply adapter or connector because the power supply is not delivered.

We tried to use HUAWEI superfast power supply adapter but we faced this problem: https://community.st.com/s/question/0D50X0000Bftpj3SQA/cant-able-to-populate-the-target-and-boot-the-image-on-stm32mp157cdk2

Thanking you!

Power supply is usually not an issue if it could provide more than 1A (more current are required only for intensive usage, but also 2A are provisioned to supply the 4 x USB Type-A of the DK2 with up to 500mA each).

With some supplies, you could see the red led blinking one or two times to indicates that the Type-C supply has not been detected as 3A (could be also because it is not 100% Type-C compliant or using a Type-A <-> Type-C cable). This is a warning only and does not stop the boot process.

Some supplies are even not detected at all as a Type-C, then the red led is kept light and the boot process is stopped.

Here are some list of tested supplies (without any ST endorsement as model could change without notice):
