Hi Bob, I am pleased to report that using the latest community BSP I have been able to get an LS1021A-TWR-PB to boot and provide a login prompt.
Poky (Yocto Project Reference Distro) 2.1.1 ls1021atwr /dev/ttyS0 ls1021atwr login: root root@ls1021atwr:~# root@ls1021atwr:~# uname -a Linux ls1021atwr 3.12.37-rt51+ls1+gf488de6 #1 SMP Wed Aug 31 13:13:11 BST 2016 armv7l armv7l armv7l GNU/Linux My original problem was an issue with the command I had saves as an environment variable in u-boot. Once that was corrected things started to work much better. My next hiccup was trying to do an NFS boot when the kernel does not seem to like starting with a static IP address. Now I am up and rolling the IP stack is at least working for a local loopback ping. > There are older versions of the Tower board with earlier (rev 1 ) silicon.

As I have got this all up and working with the latest code, I take it that I am looking at a board with the more recent silicon version on it. Regards, Thomas A. F.

I'm doing a fresh build now and can re-confirm this a little later. Which repo are you using for meta-freescale and linux-qoriq? I think using github.com/Freescale/meta-freescale.git will give workable results now. There are older versions of the Tower board with earlier (rev 1 ) silicon. I have one of these, but it's on the shelf. Bob On 08/26/2016 03:55 AM, Thomas A. F.

I did: => setenv consoledev ttyS0 After that I was able to get the netboot command I had working! Linux started up and then issued a Kernel panic. At least I have some out put to work with now though. To be honest I have no idea which kernel I just booted over NFS, it could be from the freescale SDK, a neat Yocto Fido or Krogoth with community or the one build as per the community instructions. I'll try booting with something known and see how var I get.

Please set this variable and try again.

Thorne MEng AUS MIET Sent: Thursday, August 25, 2016 8:53 PM To: [email protected]<mailto:[email protected]> Subject: [meta-freescale] Getting Started With A New freescale / NXP LS1021- TWR Good afternoon, Has anyone got a kernel from a recent release to come up on a recently produced LS1021TWR board? I have been struggling to get an LS1021-TWR board booting from images that I have generated using the community freescale. I have also tried to use the freescale SDK for the board without much success, so it seems likely there is some common fault, probably with my configuration, if not the hardware or pre-loaded binaries. I ask specifically about it being a recently produced board as it sounds as if the CPU has been updated and may not work as it did before. This is based off of some discussions I had with a distributor over the past couple of weeks. Initially I thought this was something causing an issue with just the LS1021-IOT boards and their SDKs but it sounds like both Internet Of Things and ToWeR designs are effected. I had made a post about my difficulties on the NXP Community site, but not received any comments on it yet. https://community.nxp.com/thread/432937 The post includes a summary of my issue, the environment variables that I have set and the serial output from the board. I can provide further details through this mailing list too, but I did not want to generate a huge email full of what might be irrelevant data. The short summary is that I get as far as the "Starting kernel ..." message and then see no further output from the board. This is true when trying to boot from the SD card or over NFS. If anyone can provide any suggestions or pointers I would be very grateful to hear them.
