Porting Fiasco + L4Re to Raspberry Pi 2
by Antoine DEBUT 26 Nov '17

Hello l4-hackers, I am currently working on porting the Fiasco.OC micro kernel onto the Raspberry pi 2. Therefore, I am struggling with memory mapping, and I encounter the following error when launching the default 'hello' entry: L4 Bootstrapper Build: #2 Tue Feb 23 11:57:19 CET 2016, 4.8.3 20140303 (prerelease) Scanning up to 1024 MB RAM, starting at offset 32MB Memory size is 1024MB (00000000 - 3fffffff) RAM: 0000000000000000 - 000000003fffffff: 1048576kB Total RAM: 1024MB Scanning fiasco Scanning sigma0 Scanning moe Moving up to 5 modules behind 1100000 moving module 02 { 10db000-110c4d7 } -> { 11cc000-11fd4d7 } [201944] moving module 01 { 10c9000-10da373 } -> { 11ba000-11cb373 } [70516] moving module 00 { 1043000-10c889f } -> { 1134000-11b989f } [546976] moving module 04 { 1029000-10425af } -> { 111a000-11335af } [103856] moving module 03 { 100f000-102849b } -> { 1100000-111949b } [103580] Loading fiasco Loading sigma0 Loading moe find kernel info page... found kernel info page at 0x2000 Regions of list 'regions' [ 1000, 1aff] { b00} Kern fiasco [ 2000, 92fff] { 91000} Kern fiasco [ 93000, 930eb] { ec} Root mbi_rt [ c0000, c9c33] { 9c34} Sigma0 sigma0 [ d0000, d6177] { 6178} Sigma0 sigma0 [ 140000, 16905b] { 2905c} Root moe [ 170000, 17b58b] { b58c} Root moe [ 1000000, 100e4ff] { e500} Boot bootstrap [ 1100000, 1133fff] { 34000} Root Module API Version: (87) experimental Sigma0 config ip:000c0100 sp:00000000 Roottask config ip:00140250 sp:00000000 Starting kernel fiasco at 000012b8 Non-HYP kernel detected but running in HYP mode, switching back.

I am currently working on the latest snapshot (2015123115), with U-Boot as a bootloader, and testing on a real board (Raspberry Pi 2 model B V1.1). The entry built is the standard 'hello', and I use the ramdisk-arm.rd given in the snapshot. I did add a custom Bsp for the board, mainly based on the first Raspberry Pi except for the Base Address, that is 0x3F000000 instead of the first Pi's 0x20000000. I highly think that it is an address configuration problem, because it first happened when I did expand the RAM size to 1024MB. With further investigation, I found out that it was the kernel memory allocation that causes this error, and suspect an incorrect MMU mapping. This suspicion comes from the fact that the assertion takes the address _base (0xf0400000) and the currently allocated block (0xee100000). I did not modify any parameter in the kern/arm/mem_layout-arm.cpp file on the Fiasco directory, which provides the default ARM addressing. Maybe that's where my error comes from ? How can I correctly configure my memory mapping, besides what I already configure in the Bsp (given in attachment) ? Also, it is the first time that I am assigned for porting a system, do you have some hints, like important steps to follow ? I am pretty sure it is a newbie error, but I cannot figure it out for now :( Thanks in advance for your time, -- Antoine Debut EPITA 2016 - GISTRE

Trying to run L4Linux on Cubietruck

Dear L4-hackers, I have already run "Hello World!" on Cubietruck. At the moment i am trying to run L4Linux. I have built the files on Ubuntu with cross compiler gcc-linaro-4.9.4-arm-linux-gnueabihf. During booting there are two errors, assertion failure and kernel panic.

Hi all, I want to give L4Linux access to SD card, and ethernet driver. Initially I thought by run L4Linux kernel on top of L4re, drivers built with L4Linux kernel can just work. After trying and reading the email archive, seems like I need to configure the corresponding capability in cfg. I’m very new to L4re environment is there any tutorials or references that can help me understand it better? (I’m currently reading the manual, my development board is a beagle bone black) Also I’m trying to build a L4Linux with MMC driver. My configuration is based on default arm_defconfig. I enabled * Make Linux be a Server * Bus driver for L4vbus * L4shm based network driver * MMC/SD/SDIO card support -> HW reset support for eMMC, MMC block device driver, Use bounce buffer for simple hosts, SDIO UART/GPS class support, Secure Digital Host Controller Interface Support, SDHCI platform and OF driver helper, MediaTek SD/MMC Card Interface support * DOS/FAT/NT Filesystem -> MSDOS fs support, VFAT fs support however, when it build the following errors show did I do something wrong?
