How long should it take for H32B to install new firmware? A minute, ten minutes, what?

[admin]

download firmware just about 1 minutes.

I downloaded the firmware, uploaded it to the H32B and after that pressed "Run" on the installer. After that I waited for 2-3 minutes and nothing else happened. I disconnected the RS-usb-cable and now I can't connect to H32B, it doesn't respond to pressing reset button on the device etc.

can you upload your H32B to old firmware (BIN file size <128k) for a test? maybe your board need update BOOTLOADER by Jlink USB cable. new BOOTLOADER will support >128K size firmware.

Yes, version 4.44 (if I remember correctly) worked fine.

so if you want to use newest firmware, need to update BOOTLOADER by jlink firstly. then you download BIN file via USB-RS232 cable.
