Hello,I cannot find any detail about the output type of INT1 pin in the ISM330DHCX datasheet.From what I read about the registers configuration about this pin, I thought that would be a push-pull output, but if I configure an external 10K pull-up to ...

Hello,we are making qualification stress tests on our custom STM32MP157 board. One part of these tests consist to power the board with custom ramps that simulate the worst power scenarios (as glitches, slow ramp, brownout and blackout).We use the P/N...

Hello,I'm trying the NAND boot on our STM32MP157AAB3 custom board but until today I could't make the ROM code load the tf-a image from this memory.I'm yet able to boot from uSD (SDMMC1), eMMC (SDMMC2) and serial NOR (QUADSPI). For uSD I partitioned t...

Hello Patrick,you were right, I was missing the pull-up un the bus, enabling the internal pull-up will make the timeout prints much lesser but still present.Adding external 10K pull-up has fixed the problem.Thank you for your support.Best regards,Ros...

Hello Patrick,thanks for the support.I remebered a note in the wiki page about the ROM code flash memory boot (under the ONFI parameters table) that says that the ECC can be forced even while reading the other parameters from the ONFI. So I tried to ...
