Currently it is NO problem, since I use a SAM9263 with enough SDRAM for testing, but the final version will run on a SAM7 > Alan Stern once posted a very useful sheet to decode the usbmon's > output, I saved it here: > http://people.redhat.com/zaitcev/notes/usb_stern_cheat.txt I hope it will help me... Question: How can I determiner how many memory Linux is sucking? I have the question because I have build the PDU program as kernel module and modified INIT to load a function stored in the Kernel Module and then enter an endless loop which collect the data from the I²C devices, store them for further usage... The further usage is the Request from the Host, e.g. NUT (Network UPS Tools) and pull it out as USBHID-PDU. OK it is a "gadget" driver but I have problems to get the PDU stuff running. Can you give me some hints or even links to sources from others where I can get ideas? Note: The WHOLE kernel on my "24V DC modular ATX PSU" has arround 389 kB. Could the kernel striped down to run on a 512 kB Flash plus 64kB SRAM and being executed directly without using the RAM?
