Resolved! STM32N6 - booting off Quad spi (OTP) settings
Goal boot from a Quad SPI flashI shouldn't need to change any OTP settings. Any sNor flash chip connected to XSPIM_P2 that can operated in single spi mode can be booted off from? From my understanding if we want to make a dev board and use a differe...
STM32F105 DFU Bootloader Grief
Hi all.I'm new to STM, but have been designing and making embedded MCU products for over ten years.I was drawn to the STM32F105 series because of the USB DFU, to allow for field updates for prospective customers to update a product we're developing. ...
Resolved! RM0444, Rev 6 - Minor typo in Table 17
The entry for address 0x1FFF7838 in Table 17 ( Organization of option bytes) shows FLASH_PCROP1ASR as the "Corresponding option register" - it should be FLASH_PCROP2ASR.
Resolved! In Shutdown, how is RTC powered?
While I was experimenting with the 'L476 Disco, the RM wording goes across multiple families, so it may be relevant to most/all of them. In particular, for Shutdown mode (which is supposedly the lowest-VDD-consumption mode), the RM says: What does "...
STM32U083MCT6TR, How should VDDUSB be handled when USB is not used and VDD = 1.8 V?
I’m designing a board using the STM32U083MCT6TR, and my system supply voltage is VDD = 1.8 V.The design does not use USB at all. The datasheet specifies that VDDUSB normally requires 3.0–3.6 V for USB operation, but it’s not fully clear what the corr...
Resolved! Microcontroller with some kind of audio I/O capability ?
Split from WiFi or WiFi+BT modules architecture and parts recommendations as that's really a separate question!Thank you @Andrew Neil I didn’t explain myself very clearly. The part I’m mainly interested in is the audio side — specifically, a microcon...
Resolved! STM32G071GBU6 top marking
(I tried to submit a ticket but the system seems broken, giving an obscure error about an incorrect zip code).I need to confirm which version of STM32 is placed on a board. There are two versions, GP and PD. The datasheet does not really specify how ...
STM32H753 Current Comsumption
Hello, in the STM32H753xI datasheet, Table 11, "Total current into sum of all VDD power lines (620mA)," is the voltage condition VDD = 3.3V? I would also like to know the current at VDD = 1.8V.
Resolved! Looking for a sample Hard Fault Handler that can determine the location of the fault
I have a project that is using custom hardware with a STM32G0B1CBT6 processor. The code is developed using STM32CubeIDE and STM32CubeMX. However, there are times when I am unable to run a debug session and I'm seeing (very) occasional Hard Faults.I...
