This post can be removed as I found out what was wrong...But otherwise when you want to do DDR tuning some experienced quirks:- RTFM twice!- Make sure the target board is in Engineering Boot Mode!!- Notices that latest CubeMX and STM32CubeProgrammer ...
Is there a way to build only optee, etc. up to the level of u-boot?It would help to ease board bringup, checking the dts effects, do some basic testing. Regards,Roland
I have a small micro that needs to run before the MP157 is active. The voltage coming gin is 5V, but I need 3.3V. Is there an always-on LDO in the STPMIC1 for such purpose? I assume the internal LDO is not te be used?Do I need to program the voltage ...
I have the latest FP-AI-VISION-1, the 747i-DISCO and the BCAM board. I can see the image, but cannot storen anything to a SDCARD. I tried an SDCard that is readable in the original 747i-DISCO demo code, so at least the interface and card seem to work...
STM32G0-DISCO and Power Analyser UCPD Software. I cannot see the STM32G0 disco device when attached through the micro-USB. Tried all the obvious things: Restarted, Firmware updated/reflashed, STLINK updated, tried Windows/OSX.The board/port will not ...
That will not work in my case. Just for some more background:- I use a STM32C011 that does some chores on the board next to the STM32MP157F.- One task is to provide the BOOT[2..0] pins setting instead of hard-wiring or a dip switch.- The procure is w...
It seems not to work as I hoped/expected it would be :(The BUCK3 delivers the 3.3V as already mentioned in this thread. However, the 3.3V will turn off when pressing reset. The interrupting is short (5ms on its best behavior), but for the intended pu...
Thanks for the note:I measured the -DK2 and the behavior of BUCK3, LDO2 etc and indeed the STPMIC1A is 3.3V and stable and always on. The LDO e.a. are affected when reset occurs.Tnx
Yes, it worked! Thanks for your suggestions.I tried to see if the STUSB1700 (source power supply 5V @ 3A) would emit something like "I have one PDO and capable of 3A" but that seems a bit to simple as nothing happens. So I need to dig into this subje...
