Resolved! Chinese fake chip!
China has many chip likes stm32:GD32 AMP32 etc. The bad people use laser to change the Chinese chip into STM32it is vrey bad. I also bought the fake one.

Resolved! STM32H74x/75x SDRAM (re-)mapping and caching
Hello,maybe this MCU is pretty old but... I'm designing HW for the H75x using SDRAM on bank 1 (SDCKE0+SDNE0).RM0433 table 154 shows text "SDRAM bank 1" at 0x7000.0000 and 0xC000.0000, also figure 98 but table 7 "Reserved or remap of SDRAM Bank 2".Q1:...
FDCAN interrupt lines in the manual...
I got a hard time comprehending about the two interrupt lines in the manual. I can really see a "connection" between certain sources to the interrupt lines, nor can i find a register to connect them. It seems to me, that i only can decide what interr...
New ST website is horrible.
"Modern feel and look" prevailed over usability, navigability, and common sense. The fact, that the site nags about obsolete browser is a clear indication of the level of incompetence of the creators.Should anybody from ST answer, please do so under ...
Resolved! B-U585I-IOT02A USB Host problem
I'm using BSP driver for USB PD (TCPP03-M20) on the B-U585I-IOT02A, for initialization of the USB PD as USB Host I use the following code:BSP_USBPD_PWR_Init (USBPD_PWR_TYPE_C_PORT_1); BSP_USBPD_PWR_SetRole (USBPD_PWR_TYPE_C_PORT_1, POWER_ROLE_SOURCE)...
Resolved! MCU stall after a number of continuous writes to FMC
Hello all, I faced with a big stall issue when write a number of data via FMC. I guess it is related somehow with a cashe controller, but I can be wrong.The details in brief:I use an STM32H757 std dev board with all needed corrections to apply FMC in...
Problem with sending more than 16Kbytes of data with CDC_Transmit_FS.
We are trying to send serial data from an ST microcontroller to a PC using CDC_Transmit_FS.We can send data less than 16Kbyte (4096 * 4byte) without any problem, but when we try to send larger size, sometimes we get USBD_STATUS_CANCELED (confirmed by...
USB AUDIO DEVICE CLASS working in Full Speed, not in High Speed
I am looking to create a USB to I2S/TDM interface.I generated a Full Speed USB AUDIO DEVICE skeleton from CUBE MX.I made some changes and I have working code in FS.I generated a skeleton in High Speed. I made the same changes and it doesn't work. T...
This is an issue related to the initialization of the X-CUBE-SMBUS middleware during code initialization.
I have encountered an issue when I tried to use CubeMX to generate code. At the start of a new project, I selected I2C (SMBUS-Alert-mode) and used the X-CUBE-SMBUS middleware. However, some issues occurred during code initialization. In main.c, it do...
