I am currently attempting to use the USBD drivers for the STM32F765 in order to communicate over USB C as a virtual com port. I get to the point where my computer recognizes the device and the driver that is necessary, therefore the control transfer ...
I see that there is a function to write SDRAM ( HAL_SDRAM_Write_32b ) but no FLASH.I want to take data from ADC array[2000] and save so I do not loose when it is powered down.And of course recall / display it later.
Hi,I need to write a bootloader which will load the new program from a USB memory stick.Unfortunately I cannot use the ROM based DFU bootloader.The bootloader would need to be held in FLASH and protected against update. Easy enough.I believe that the...
Hi, I'm using latest FW STM32Cube_FW_L4_V1.13.0 and the PWR_STOP2_RTC example seems to fail waking from sleep mode. It goes to sleep after 5 s alright and power consumption drops from cca 11 mA to 4 uA but after cca 33 s, as stated in readme, nothing...
Posted on November 19, 2015 at 20:35The AN4286.pdf SPI Bootloader application note specifies two different commands for erasing flash. On page 24 it specifies 0x44 with checksum 0xBB. However, on page 25 the datasheet specifies 0x43 with a checksum ...
I may be mistaken but It appears that the HAL is not computing the correct value for the RD_RWN bit as defined line 6319 of the file stm32l4xx_hal_i2c.c:/** * @brief Handles I2Cx communication when starting transfer or during transfer (TC or TCR f...
Hi AllCan anyone explain this?I have a USB FS device driver which works as USB-MSD class but when I try to use the same driver for USB-CDC class it fails when the USB host sends a specific control transfer consisting of a SETUP token followed by a no...
I am using the USBD driver provided by your company to communicate via USB as a virtual com port in STMCube32_FW_F7_V1.7.0. I am using the STM32F7 series. When I receive messages, the buffer fills with additional characters at the end. I have not edi...
I am trying to employ the ST bootloader to upgrade firmware over UART. Problem is, the bootloader refuse to run when called from the application. Based on a debugger log it returns after doing some condition check. I don't know ARM commands to tell w...
I use __HAL_SYSCFG_REMAPMEMORY_SRAM(); this function ,but MX_USB_DEVICE_Init(); can't work.After I went to debug tool ,it appear cannot access memory this problem.I don't know how to solve it.Maybe it should register address problem,or init address ...
