i.MX6 quad booting problems
by Will Korteland 25 Dec '14

25 Dec '14

Hi everyone, I hope I'm using the correct list for this type of thing... I've bought my own Sabre Lite (identical to the AOS boards), and I've been trying for a few days now to get it to boot from tftp. I've downloaded the prebuilt u-boot.bin from the Sabre Lite hardware page, but it still doesn't seem to be working - it keeps timing out when trying to do the transfer. I think my tftp server is set up correctly, since it is the same as it was during AOS last semester. Could someone please boot a Sabre Lite set up for TFTP, interrupt the default boot process, type "printenv" into the U-Boot prompt and paste the results? Sorry if this is the wrong place to ask. Thanks, - Will

Is there no "execute" permission that can be set (or not set) on mapped pages in sel4?

Hi Will, About the message, "Unknown command 'bootelf'", it seems that this command wasn't configured and compiled. You'd better recompile th u-boot image. You can modify the source code to config this command. Add a macro define "#define CONFIG_CMD_ELF" in the file "include/config_cmd_default.h" to enable the command "bootelf". This link can help you, http://elastos.org/redmine/issues/17472#change-34139. Lucky! -- Jensen Zhang Tongji University

Run seL4 on OMAP4
by 张静轩 22 Dec '14

22 Dec '14

Hi, We have run the seL4 on pandaboard[1] (omap4 platform). It seems that the kernel works well, excpet for some tests about timer. Is there anyone interested in it or helping us? The source code can be got from the following link[2] now. (We will upload to github latter.) btw. I think the devices and platforms supported by seL4 are too few. How to make it easy to let seL4 support more devices? Can anyone give me some suggestion? I suggest to write a document to port seL4 easier. :) --- Jensen Zhang Tongji University 2014/12/22 [1] http://pandaboard.org/ [2] http://elastos.org/review/#/admin/projects/HD-Elastos

Re: [seL4] Devel Digest, Vol 7, Issue 3

Hi Pei, Maybe you could make it happen on cmkes. As far as I know it's a set of OS' services for sel4, just like Iguana for OKL4. FS should be a service, so I think it's better ported into cmkes. This email is typed on my iPhone.

Hi, Who wrote the program in file $/libplatsupport/plat_include/omap4/platsupport/plat/gpt_constants.h , GPT4_DEFICE_PADDR is wrong spelled, it should be GPT1_DEVICE_PADDR. static void *paddrs[] = {(void *) GPT1_DEVICE_PADDR, (void *) GPT2_DEFICE_PADDR, (void *) GPT3_DEFICE_PADDR, (void *) GPT4_DEFICE_PADDR, (void *) GPT5_DEFICE_PADDR, (void *) GPT6_DEFICE_PADDR, (void *) GPT7_DEFICE_PADDR, (void *) GPT8_DEFICE_PADDR, (void *) GPT9_DEFICE_PADDR, (void *) GPT10_DEFICE_PADDR, (void *) GPT11_DEFICE_PADDR}; Xilong Pei Tongji University 2014/11/19

Confused on porting/using musl lib c
by chengkunck＠gmail.com 27 Nov '14

27 Nov '14

Hi All, I want to use musl lib c but I'm a little confused on the following two projects: libmuslc and musllibc. I went through their Kconfig and brief intros, so my question now is do I need them both to port/use musl lib c on sel4? It might be a dumb question but I'm stuck here, any help is appreciated. Best regards, Kenneth
