memory backup within strict time limit (10s max) on STM32L4R9
Hello everyone,I’m currently working on developing a bootloader, and I’m trying to implement a memory backup function. My goal is to copy 158 pages of 4 KB from BANK1 to BANK2.I’ve written software that uses the standard copy function with FLASH_TYP...
Resolved! stm32H743zi pin configuration
My hardware has the I2C pins (SDA and SCL) connected incorrectly, and I cannot change them because the hardware is already built. Is there any way I can fix this issue from the firmware side? Can I change the pins through software? hear attach my sch...
STLINK V3 RX/TX direction?
On the STDC connector, Pin 13/14 are virtual com port signals T_VCP_RX and _TX.Which one is input and output? They have cryptic comments like "Output for STLINK-V3SET" (for _RX) - Is RX an output and connects to the RX pin on the STM32? Or is it an i...
Resolved! STM32H563RG VCAP connection
For product A (68-pin VFQFN package), pins 31 and 66 are VCAP pins, and 2.2uF capacitors have been placed on each pin. Should pins 33 and 66 be connected to each other, or is it sufficient to place the capacitors on each pin individually?
STM32H745 Dual Core bootloader application
Hi,I am using stm32h745 dual core microcontroller. I want to bootloader application in this processor. The same process does not work with applications made with single core. Can anyone share a sample code for this? Or can you help me on how to apply...
Resolved! HAL_I2C_Mem_Write with 24LC01B EEPROM
Hi there!here i'm for ask another help. I use STM32G031 for write and read eeprom 24LC01B , and i work with where Address = 0x01;HAL_I2C_Mem_Write(hi2c, DevAddress, Address , I2C_MEMADD_SIZE_8BIT, &val, 1, 100);so if i wrote 7 byte everythingh work p...
Resolved! STM32U5G9J-DK1 signal levels
I am designing interface board similar to MB1835 for our touchscreen to work with MB1829. STM32U5G9NJH6Q power supply VDD, VDDA, VDDIO and VDDUSB are all supplied with 1.8V. Thus, STM32U5G9NJH6Q GPIO is compatible with 1.8V signals. Touch Screen co...
STLINK-V3 manual control of SWCLK (BOOT0)
Hello all,I would like to set SWCLK to permanent logic high, from pc side, in order to force bootloader loading in my custom board.Is that possible?Edit. Is any of the ST-link output signals (SWCLK/TCK, SWDIO/TMS, TDI) in strong logic high state by d...
