Hello,I am trying to implement the DFU protocol in an Android app. I am following AN3156.I am using UsbDeviceConnection class for the control transfer in android. I am able to write to the memory to any address using the routines described in AN3156 ...

Hello,I am trying to transmit some data on my STM32F042F6P6. But my PC's serial monitor only picks up some of it. Here is the code and the serial monitor output:void readAllRegs(void){ uint8_t value; for (uint8_t addr = 0x00; addr <= 0x2E; addr++...

Hello everyone,I am trying to use both USB CDC and SPI on a STM32F042F6P6 MCU. Unfortunately, without even writing almost any code (just an HAL_SPI_TransmitReceive() and a CDC_Transmit_FS()) it says the flash memory overflows by 1484 bytes.Is this no...

Hello everyone,I am having trouble communicating with CC1101 radio SPI slave. With HAL, the transfers work well and I am able to read every register, but because I am using stm32f042 MCU, I'm low on flash memory because I'm also using USB CDC. So I'm...

Hello,I have problems with building the cdc_msc example on STM32CubeIDE. My board is STM32F411 blackpill.I have followed the instructions in https://github.com/hathach/tinyusb/discussions/633 but get errors when building.Below I will link my entire p...

Hello again,Today I successfully read the first 2 blocks of 2048 bytes.My confusion was I thought wTransferSize was a variable we could specify through wLength (the number of bytes to read, so I thought it was also the block size). But turns out I wa...

I will try soon to use libusb on my stm32 device to sniff the packets and debugg this, before implementing the logic in my Android app. I'll then post all the packet transactions.

Hello, thank you for your help.I did find a way to avoid the USB communication error. I changed my clearWaitIDLE function:public void clearWaitIDLE(DfuStatus dfuStatus) throws Exception { do { clearStatus(); getStatus(dfuStatus); ...

Of course they are, how else would the commands I mentioned all be working? As I said, the problem is that setting the address pointer before a DFU_UPLOAD command is issued (for reading at that address) is what messes up the communication for some re...

Ok thanks, I was using CDC_Transmit_FS() as a serial.print() equivalent of the arduino, I will look at some examples on how to properly implement it.I tried the following which seems to fix the issue:int _write(int file, char *ptr, int len){ while(C...
