pio\build\genericSTM32F103CB\firmware.binĪVAILABLE: blackmagic, cmsis-dap, dfu, jlink, serial, stlink pio\build\genericSTM32F103CB\firmware.elfĪdvanced Memory Usage is available via "PlatformIO Home > Project Inspect" I followed the exact procedure I have posted above and I have no problems uploading via DFU. thank youĭo you see a “Maple Serial” device in the device manager? platform.ini is setup toĭo i miss something? any help would be wonderful. I use the real STM32f103CB (128k) mcu on my board, not the bluepill. which are the right files i need to change? I already tried to change some file´s content which seems to be the right place but it doesnt lead me to success. so how can i change by build this way i get able to upload a bin via USB-DISK starting my application firmware from 0x08003080 as mentioned on the uTasker website. Iam then able to put my bin on the board but the flash start adress differs from the uTasker needed ones. If flashed with this i plug my board via usb to the computer and it is recognized as USB-DISK. There also exist this bootloader from uTasker: do i need to change something? which bootloader is needed? the small one starting from 0x08002000 and the one from 0x08004000. Iam able to upload the firmware bin (looks like iam able cuz there is a progress bar and info popup) i then connect my board via usb to the pc and enable connection betweend this side and my stm32 board: the firmware then is buld to set start adress to x08004000. i try roger´s bootloader, set core to MAPLE and upload method to DFU.

i'm not sure how that is done in usb-composite, you may like ot use these as clues and review the codes.I want to know how i can modify the build of my program this way, the compiled software is linked to a specific flash address. You would also need an implementation to handle those multiple endpoints.

If you need to implement multiple serial connections, more of the sets of similar endpoints is needed. Normally, i've tried it and for usb-serial (cdc acm) there are basically 3 bulk in out endpoints used, one endpoint is IN for sending data to the host, one is OUT for receiving data from the host. You could observe how the comms occur and how the descriptors are declared. this is the usb stack that ST provides a driver for as well. so the next thing is you'd need to respond on the relevant usb endpoints that you declared your descriptors for. Normally, there is a hierarchy where you have the device and within each device there can be multiple interfaces, so there could be multiple different device/interface descriptors.ĭevice/interface descriptors are merely a bunch of data, you could literally hard code it in structures and send it when a get_descriptor usb request is received.īut 'descriptors' alone merely describe the interface. It partly has to do with 'device descriptors', 'device descriptors' tells the host what to expect of the device. The usb protocols are mostly documented at
This would help you understand the codes at least.

For usb rather than using 'libraries', at some point one should go back to 'first principles' to figure out how to implement a usb protocol from scratch.
