    FreeRTOS on Zybo

    Hello Everyone, This is just for reference. FreeRTOS running on the Zybo. I could not find any FreeRTOS based post on this forum so i thought this might help anyone trying to attempt the same...
  2. Hello lestrigonac, The DTS file is here. Could have attached it, but it did not allow me....[Error You aren't permitted to upload this kind of file] I hope your SD card is formatted as per the instructions here: Place everything in the first partition. Hope this helps Regards - C.S
  3. Kernel finally booted !! Changed the bootargs in zynq-zybo.dts to: bootargs = "console=ttyPS0,115200 root=/dev/ram0 rw earlyprintk rootwait devtmps.mount=1" Then use the dtc utility to build the devicetree.dtb, do the rest of the stuff in the tutorial and watch the kernel boot. ..then make a bonfire and dance around it...
  4. make it yourself : dd if=/dev/zero of=ramdisk.image bs=1024 count=8192mke2fs -F ramdisk.image -L "ramdisk" -b 1024 -m 0tune2fs ramdisk.image -i 0chmod a+rwx ramdisk.image OR Try using the one given on ZedBoard product page...i am not sure if it will work... I hope it helps.. I compiled my own kernel and Uboot and used that ramdisk, now i get the following problem.. [ 0.000000] bootconsole [earlycon0] enabled[ 0.000000] INITRD: 0x00800000+0x00800000 overlaps in-use memory region - disabling initrd[ 0.000000] cma: CMA: reserved 128 MiB at 17800000 ... [ 1.376497] No filesystem could mount root, tried: ext3 ext2 ext4 vfat msdos[ 1.383682] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
  5. Just tried make CROSS_COMPILE --- ........... -- zynq_zybo_config with the ZYBO in !! Someone please update the PDF file now.
  6. I've een going through the Zybo Embedded Hands on Tutorial and I ------ - Cannot find zynq_ZYBO_config file for compiling UBOOT. It's not there in the master and master-next branch.... - Cannot find ramdisk Image on ZYBO webpage... - Cannot proceed further... IMHO the "tutorial" is not organized properly at all... Is anyone at Digilent maintaining / reviewing all these documents before putting them up on the internet ? Can anyone provide these files if they have ? Thank You....
