I'm porting some fully functional older CMSIS firmware to STMCube and TrueStudio. The old report is 363 bytes which compiles, but Windows Device Manager detects an error in the Report Descriptor. After some tinkering, setting USBD_CUSTOM_HID_REPORT_D...

Posted on October 02, 2016 at 20:39I have a very basic F103VET dev board, with the schematic. The board arrived running what I guess was ST-Link, which I don't use. I was able to erase the Flash using the latest FlashLoader (FL) v2.8, via the Cmd l...

Posted on April 30, 2015 at 21:02I have two almost identical 72MHz boards which have code issues I suspect are related. I have DFU firmware that loads on to both boards, and both appear to the host as a USB DFU device. App firmware is loaded at 0x08...

USBD_CUSTOM_HID_REPORT_DESC_SIZE is used in the Config Descriptors, and requires two bytes. The generated code isUSBD_CUSTOM_HID_REPORT_DESC_SIZE, /* wItemLength */0x00,which is OK if the value is <= 255. If greater, the [-Woverflow] compiler wa...

OK, found it, my error. After pasting the old descriptor into the MX code, an edit deleted 2 bytes from one of the reports. All is now well. Lesson learned: make sure the byte count is correct, and edit carefully. Sigh!

Pavel, thanks for the reply. The generated array size definition code is__ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE] __ALIGN_END ={...}and for USBD_CUSTOM_HID_REPORT_DESC_SIZE = 361, 362 and 363, as I unders...

Posted on October 06, 2016 at 16:47OK, using JTAG + openOCD I can load firmware. This was the original goal, and the project now moves along, finally. Why the ZET chip won't load using FlashLoader is still unknown, but it's really now a non-issue. ...

Posted on October 03, 2016 at 20:36FlashLoader 2.8 list the default COMMS as 57600 8E. Experiments with the commands shows the F103ZET loader is happy with 115200 8E/8O but not 8N. I had not noticed that the default parity is EVEN. I tried the board...
