ZFlasher STM32

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!!!

Does what I needed surprisingly simply. I was amazed could use my otg adapter and a st-link tool to erase and flash a new hex file to a chip that now flies a toy drone like it's a professional racing quadcopter! My pc died and this free app helps me to continue my love of tinkering

It has worked fine 2-3 times after donation and after that it is using error. error Log "failed to find st link v1 by VID:PID Could not link st link device". On home/main page st link is showing connected. Please help me out. I am using st link v2

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.

Works on Pixel 2 XL without issue. Much easier than dealing with a pos pc!😁👍👍👍

needs some improvement. It erases all the sectors of flash. Should limit to erasing only the pages required

Use "stlinkp app" that works well ..this zflasher has problem in connecting and detecting device

Perfect function and great user Interface

donated for stm32l083rz. The app detected mcu but unable to flash.

Great opening but just starting lets hope it can hold this five star?

Limitation to load very small side firmware...

Works ok for stm32f405

Works well but requires a donation.

The app pretends to be free but then requires a "donation"

asking for donations even after donating. i am using stm32f0 series

NITHIN and other companies have a lot

Excellent i love it

More than handy !

Asking for donations eventhough paid for STM 32F0
