Hi to all, I am trying to build a USB host application based STM32F105 using USB stack by Keil (RL-ARM 4.13 (USB Host Mass Storage Class Interface). But I can not even run the MSC demo - fopen() always returns NULL. Besides of it, the USB stack does not recognize mass storage devices bigger than 1G! Does anyone have any experience with this software package? Regards Alex
So what was the problem?
I suppose, USB-Host library in RL-ARM version 4.13 was not "brewed" well... We are going to purchase v4.20 anyway, hoping it will solve the problem.
