Hello,

The demonstration application for the  STM3241G-EVAL Evaluation board was erased and I am trying to reprogram it back using USB flash drive. I followed the steps and still was not able to see progress in the LCD.

1). Jumper configuration was checked as per the datasheet. But for the boot mode the BOOT0 and BOOT1 should be 1<->2 but I see on the board there is either 0 or 1. what should I do now? and please help me what should be the BOOT0 and BOOT1 be set to ?

2). I copied the dfu file to the flash drive and then connected it to the board using the Micro-AB to standard receptacle A connector to the USB OTG HS pin. Is it correct ?

No, that's not how DFU mode works. You need to run the DfuSe utility from Windows.

The BOOT0 switch should be in the 1 position (right), the System Loader will want to use the USB-FS connector.

I'm sure most of this stuff is documented.
