Adding Zynq platform support to base-hw
by Johannes Schlatow 19 Dec '14

19 Dec '14

Hey, I just started adding support for the Zynq SoC to base-hw (see [1]). As I don't have any Zynq hardware available yet, I tried running this on QEMU 2.1.2; I compiled the run/hw_info target. After applying some printf debugging ;), I figured out that the program dies (i.e. QEMU freezes) during kernel initialisation in init_virt_kernel(). I therefore tried attaching gdb to QEMU's internal gdb server, however, it seems to ignore my breakpoints. Hence my question: Do you guys have any experience with low-level/kernel debugging on QEMU? Maybe I am missing something or QEMU is just weird? [1] https://github.com/ValiValpas/genode/commit/4e375384d635d06626f0b226ac14e21… Cheers Johannes

USB Armory - an interesting platform for Genode
by Norman Feske 18 Dec '14

18 Dec '14

Hello, I just was made aware of a crowd-funding campaign for an open hardware platform called USB Armory, which would provide an intriguing playground for Genode: https://www.crowdsupply.com/inverse-path/usb-armory In short, USB Armory is an i.MX53-based computer in the form factor of a USB stick. It is meant for security applications such as VPNs, authentication tokens, and encrypted storage. It is based on the FreeScale i.MX53 SoC, which it is well supported by Genode, i.e., Genode can be used as secure-world OS besides Linux running in the normal world. Personally, I find the project interesting because it strives to be an 100% open platform, which includes hardware, software, and firmware. Hence, at Genode Labs, we already started investigating possible Genode-based applications for it. As of now, the campaign has reached about 55% of the funding goal. If you are interested in such a platform, please consider joining in to make it happen. Cheers Norman -- Dr.-Ing.

AHCI
by Nobody III 16 Dec '14

Is the Genode AHCI driver supposed to announce service "Block"? I've seen the AHCI test script, but it fails. Is there any scenario in which the driver is known to work?

tz_vmm : VM access a address which isn't allowed

Hi all, I am trying to run *tz_vmm* script on the *imx6 platform*. In which I have tried to put Genode (without trustzone) OS image instead of linux image as a guest OS which is configured according to normal world. we changed the CSU also according to imx6 security manual.

Also, tried to compile the image by changing this address to 0x10001000 in the file spec_hw_imx6.mk file (for the normal world OS image). We get the same error as above but only with the memory address changed in the error message. Kindly let us know the possible reasons behind getting this error. Thanks in advance.

Simple test kernel for the non-secure world
by Mahdi Aichouch 16 Dec '14

16 Dec '14

Hello, I am trying to test the bare-hw tz_vmm on i.mx6. >From the article about Genode and trustzone, I read the that there is a simple test kernel that was used test the switch from the normal world to secure world. Is this simple test kernel available somewhere? Thanks in advance. Best regards, Mahdi
