I'm trying to test writing my own DFU client and I have the simplest of code to start with, see below:
#include <CubeProgrammer_API.h>
int main()
{
dfuDeviceInfo* dfuList = nullptr;
// Enumerate the available DFU devices
int iCount = ::getDfuDeviceList(&dfuList, 0xDF11, 0x0483);
if (iCount != 1)
{
return 0xFFFFFFFF;
}
int iResult;
//#define TRY_VERSION_2
#if defined(TRY_VERSION_2)
dfuConnectParameters params;
params.usb_index = dfuList[0].usbIndex;
params.rdu = 0;
params.tzenreg = 0;
if ((iResult = ::connectDfuBootloader2(/*m_pDFUDeviceUSBIndex*/params)) != 0)
#else
if ((iResult = connectDfuBootloader(dfuList[0].usbIndex)) != 0)
#endif /* TRY_VERSION_2 */
{
::deleteInterfaceList();
return 0xFFFFFFFF;
}
::disconnect();
::deleteInterfaceList();
return 0;
}
connectDfuBootloader and connectDfuBootloader2 always return:
/** Operation not supported or unimplemented on this interface */
CUBEPROGRAMMER_ERROR_NOT_SUPPORTED = -5,
I'm building in VS2022, x64 on Win11. The getDfuDeviceList call succeeds. When using CubeProgrammer itself, I can connect to the device as well as download an ELF file (see this thread here - https://community.st.com/t5/stm32cubeprogrammer-mcus/stm32h7-jump-to-bootloader-not-working/td-p/799726)
Why would the API be failing?
Thanks,
