omap3 usb platform and other
by Vasily Sartakov 02 Nov '11

02 Nov '11

Hello. I would like to discuss with you platforms supported in l4linux. l4linux good working on "vanilla" arm platform, but when we try to use a board specific devices - for example USB, we have some problem with full device support in sources. For example, USB gadget need musb, witch need twl4030, which need i2c, which need clock and power domain initialisation, and all of this part placed in arch/arm/omap. In next mail attachment you can find the our kernel, which support usb on Overo Gumstix … [View More]

Running L4 linux on Beagle board

Hello, I tried to run L4linux on a beagle board. I downloaded the snapshot, did Make setup (I chose config for beagleBoard) Make I compiled quiet well but I can't launch le L4linux on my qemu (Maybe I did something wrong), I'm currently using qemu-linaro (last release) Qemu-system-arm -M beagle -m512 -kernel obj/l4/arm-beagleboard/images/bootstrap_L4Linux_ARM.elf -initrd files/ramdisks-arm.rd And I get this error: Qemu:Hardware error: no boot device found CPU#0 {… [View More]

Mouse and keyboard on L4Android
by Giorgio Wicklein 19 Oct '11

19 Oct '11

Hi, Short: how to get an USB mouse/keyboard working on L4Re? Long: I'm having some difficulties to get my keyboard and mouse on a beagleboard working. I noticed that the io file of the realview-eb includes the keyboard and mouse hardware addresses, since they are mapped to dedicated registers [1] on this board. The beagleboard doesn't have such registers. Found only USB EHCI register addresses and the related interrupt number. So, I'm trying to connect an USB mouse and USB keyboard over the … [View More]

v_insert() in Mem_space class for ARM architecture
by Jung Hyun Yoo 19 Oct '11

19 Oct '11

Hi, During looking into the source code of v_insert() function in mem_space-arm.cpp file, I found two cases where it returns improper Mem_space::Status. Case #1 When the size parameter of v_insert() is 0x100000 (that is, section mapping is asked), and the entry in the corresponding first-level page table indicates a coarse second-level page table (that is, it’s already valid) and only the entry in the second-level table is invalid: v_insert() function returns Insert_OK status. But it … [View More]

l4sigma0_map_iomem Allowed Addresses
by Wesley Miaw 18 Oct '11

18 Oct '11

I'm having some trouble understanding the acceptable values usable in a call to l4sigma0_map_iomem. It looks like the way for me to request a map from an available physical address block to a virtual memory address that can be used by the program. Perhaps I am lacking a more fundamental understanding of the ARM memory model. But what addresses should be allowed? My Verstaile Express board has 1GB RAM starting at physical address 0x60000000 but I can't use this address. I immediately get an … [View More]

Is there a way to build a non-PIC shared library with l4env?
by Valery V. Sedletski 17 Oct '11

17 Oct '11

Hi, I am trying to establish a shared arena for loading DLL's, i.e. a shared memory region, in which DLL's are loaded at the same address in each address space. I also need some ELF shared library loaded at fixed address, so I could call routines in .so from these DLL's (yes, a mixed case: LX format DLL's calling an ELF shared object, this shared object is a client library for some servers, and I want to call their API's from DLL's). So, I intend to load a shared oblect at fixed address to … [View More]
