I am trying to develop an application in C/C++ (QT) to perform an ISO 15693 R2H FTM data transfer with an STDV04 tag using the STR25R3111DISCOComm DLL. I am able to link to the DLL, connect to the DISCO board and perform a passive read on my tag usin...

Hi,I am having a problem using Read Out Protection on the STM32F405VE processorMy firmware has a proprietary bootloader which is stored at 0x8000000. It basically checks to see if a USB OTG lead is plugged in and if so attempts to access a mass stora...

Posted on November 10, 2017 at 16:28I have recently added USB support to a product, using the STM32_USB_Host_Library MSC class taken from the STM32Cube_FW_F2_V1.7.0 examples.We successfully detect devices and write and read from the disk until we ge...

Posted on February 25, 2016 at 19:03Hi, I have hit a rather strange problem that has completely stumped me!I have a really simple bootloader for the STM32L100 device which uses the USB DFU interface to copy new firmware into the flash. The bootloade...

Ulysses,Yes that was it! - I had a loop to send the commands and I was not resetting the rxSize each iteration, so it was always being sent as the size returned by the previous command. That was fine until it became too small for the next command :)J...

Posted on November 13, 2017 at 15:26It appears that the interface is in a stalled state - A callback is made to void HAL_HCD_HC_NotifyURBChange_Callback(HCD_HandleTypeDef *hhcd, uint8_t chnum, HCD_URBStateTypeDef urb_state)But why would this happen ...

Posted on March 29, 2017 at 10:51Hi,I am having the same problem. I have an STM32F205VE and an STM32F746IG linked using SPI (three wire, software CS) and a GPIO handshake line. I am performing DMA transfers using the HAL_SPI_TransmitReceive_DMA() tr...

Posted on March 17, 2016 at 12:05Did anyone ever find an answer to this? I have exactly the same problem with an STM32F205VE. I can read and write from the battery backed up SRAM just fine until I implement USB VCP. As soon as the USB stack is initi...

Posted on February 26, 2016 at 16:09Fixed it!!The st library function FLASH_ProgramHalfPage() has __RAM_FUNC in front of it! That tells the linker to place the code in section .RamFunc rather than section .text. My linker definition file did not hav...
