Hi everyone,Has anyone interfaced the Micron MT35XU02GCBA2G12-0AUT (2 Gbit xccela Flash) with the STM32N6 XSPI controller? I would like to know if it works with the existing Macronix presets or needs custom XSPI settings.Any working example or exper...
Hello,Using a NUCLEO H7S3L8, I'm trying to run a test where, using circular DMA with a linked list, I'm trying to send a buffer in memory over to the SAI for audio playback, using an external DAC. This configuration is based on either other tutorials...
Hi everyone,Has anyone interfaced the MX66UW1G45GXDI00 (1Gbit octal SPI Flash) with the STM32N6 XSPI controller?Any working example or experience would help.Thanks!
I am working on a project to connect QSPI flash memory to a PC as a USB mass storage device (MSC) using USBX, FILEX, LVLX, and THREADX on an STM32. This setup should allow the QSPI flash to appear as a drive in Windows.Previously, I successfully impl...
Hi,I would greatly appreciate it if someone could share their thoughts here and let me know if my understanding is correct.Question 1. The STM32H573 supports both USB Host and Device, but why are “USB_OTG_FS” or “USB_DRD_FS” not visible in CubeMX?It ...
I have three questions regarding the STM32U083RC： 1.Why is the reset value of EXTI_IMR1 register 0xFFF80000？The EXTI line 19-21 is configurable lines。 2.I encountered a problem: when I used the NUCLEO-U083RC demo program to PWR_STOP2_RTC, I found th...
Dear All, I am having difficulty with the Bootloader on an STM32469.It is on a custom PCB (which works fine in all other respects), and I can use the SWD interface via J-Link perfectly OK (with both STM32CubeIDE and STM32CubeProgrammer).My starting p...
So I am reading the RM0008 Reference manual because I need to describe some limits for my systemI am looking for the UARTs tolerance of clock drifton page 800 I am confused by these tables: In my case DIV_FRACTION is different from 0 and the M bit is...
