Ratings and reviews

"big" flash sizes are available only after donation, but then it works well

Works perfectly. Recognised and flashed my STM32F7 discovery board without any hiccups. If you donate remember to restart the app so it unlocks the rest of the MCU :) will spare you frustration of the "premium" MCUs not working! Thanks for an awesome app!!!

I donated, it then allowed me to connect but "programmed with some errors". Corrupted the flash, managed to recover with a laptop. st vid = 0x0483 (expect 0x0483) stlink pid = 0x3748 stlink version = 0x2 jtag version = 0x23 swim version = 0x7 stlink current mode: mass JTAG/SWD freq set to 0 stlink current mode: mass stlink current mode: debug (jtag or swd) Loading device parameters.... core_id = 0x2ba01477 F4xx: 192 KiB SRAM, 1024 KiB flash in at least 16 KiB pages.
