WEBINAR: Register today to learn how performance analysis assists with developing extraordinary experiences on the STM32MP1
Whether it's to minimize computational power, improve the device's output or keep the GUI from freezing or crashing, debugging embedded software can be a challenging and time-consuming step in the process of developing embedded devices.With a multitu...
Creating embedded graphics on your STM32MP1 projects just got easier.
We've created a bunch of sample touch screen apps in our Storyboard ST GUI builder software that you can download, and save to your hardware. In moments, you'll be able to visualize and interact with a fully-functional sample touch screen application...
eMMC boot failure / boot rom
Dear community,we got a problem booting from our eMMC (THGBMJG9C8LBAU8) memory and we cannot figure out how to solve it. The Silicon Revision seem to be "Z". Attached you can the the ping pong between MPU (STM32MP151A) and eMMC. The initialization se...
Resolved! Is there a way to increase RAM on STM32mp157C ?
Hello,We want to transfer a project from STM32F7 to STM32MP157C ( cortex M4 side). To do that we need an external RAM (arround 20 Mbytes). Is there a way to map an external RAM on cortex M4 side with cubeMX ?Best regards,Arnaud
Questions about STM32MP157C-DK2
Hello! I have just discovered that kit I would like to use to develop a new testing system within the company where I am working. However, I have some questions about it:What kind of additional card could we use to apply 24V to the board's input (I h...
