STM32 USB-PD Power Delivery Software Expansion

[FaikN]

Hey,

I am working on one of the example projects that is provided as part of USB-PD software expansion, by using SW4STM32 toolchain. I am using TCPM-TCPC architecture. During initialisation i am having errors for PE_Init. Does anyone have followed a similar topology and can help me on how to tackle with this problem? Thanks.

Hello

Could you please precise the version of the expansion package you are using?

Do you just have an error of PE_Init or is it a timeout to initialize the TCPC component?

Normal stack calling of expansion package STM32CubeExpansion_USBPD_F0_V2.1.0:

Hey Yohann,

I have fixed the problem. I have been using F0.V2.1.0; it was actually during the initialisation of TCPC component. now fixed. Indeed thanks for your response. I will contact promptly if there are other issues. Regards,

hey Yohann,

I have recently a USPD_MALLOCERROR from the initialisation function of USBPD_TCPM_HWInit function; that initialises the TCPC. What can be the reason for the malloc error in this function? and what can be the solutions?

Thanks,

Faik
