Re: Connection problem with eBay board

No, I haven't checked errata. But REV_ID & DEV_ID are same. I have 2 pcs older and 2 pcs newer boards, all the same smaller F407VGT6 type, maybe I'll test some day if the others are working or not.

Code: Select all

sprintf(Buf, "REVID: %u DEVID: %u\r\n",  HAL_GetREVID(), HAL_GetDEVID());
	CDC_Transmit_FS(Buf, strlen(Buf));
Code prints REVID & DEVID and transmit them to USB driver.

Maybe I'm not interested in testing this problem any more. I continue my project with a working board. Before I found solution there were too many "moving parts". Now there is a brighter way to go.

If You ask google "HAL_GetREVID", you find intresting stories.
