Hi,

Hi,

I consider the current git head to be a release candidate for the upcoming 0.10 release of dfu-util, so I would be glad to see some testing on various devices. I have tested on STM32F4 and will test some custom IAP bootloaders. There are still known issues on STM32L4 and STMF0, but that has to wait for later releases.

Built from git://git.code.sf.net/p/dfu-util/dfu-util.

It seem that the -Z switch is ignored, no matter the value I specify the data transferred from the device is 16384.

~/dfu-util.git$ ./src/dfu-util -a0 -Z 1000 -U /tmp/stm32.dfu dfu-util 0.9
