    First WiFi Loco-Nodes, ready for fabrication/assembly

    we've successfully merged a Linux 3.0 kernel with our 2.6.35.4 version for MMC support. it hangs but we now have complete source code to debug the eMMC is set so it does not boot, we can use this new driver to enable it so the CPU will boot from it once this is up, there are only two...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    still debugging some eCSD patches, the latest has Linux 3.0 drivers merged with our kernel for the eMMC working on a bit bang for it too started an install with a Bowser product, the factory electronics are below this was all removed, the Loco-Node is seen to the left motor connections...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    we have a patch, debugging it now kinda sorta figured it all out, editing the eCSD register will enable it to respond to boot commands from the CPU if this works, we are on the downward slide the rest is cleaning up stuff we've already compilied

    First WiFi Loco-Nodes, ready for fabrication/assembly

    We got the flashing tool working, we can now upload files to SDRAM after USB booting The eMMC will mount, we can copy files to it and they remain in place after shutdown The next and what seems like the biggest hurdle is editing the extended_CSD settings The eMMC ships from the factory with...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    forgot we already had a flashing tool configured for UART to SDRAM we made a few months ago, I have everybody digging up the files, my hard drive crash erased what I had this will enable us to move a full conprog.bin or any other file under 32 MB to /usr in SDRAM, then we use our move.sh file...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    Juan and I played a bit last night on the eMMC, we got some tools installed in the kernel to format, create partitions, etc. I also now have a full development suit again after my hard drive failed a few weeks ago, with Virtual Machine up and running which will speed things up as Ilya or Juan...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    We rediscovered a cool feature of the CPU, it has IRB (Internal Boot ROM) already embedded which makes everything clear now This is why the SPINAND didn't work. It goes through a list of ports and tries to find data at address 0. The problem with V1.4 was its flash, even though we could...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    Above is an image of the new V1.5 update, as previously stated, the faults from V1.4 appear to have been corrected Right now, we're focusing on the boot loader Here are some features: This is a IoT/IoE product for your locomotive and home layout. The intention is to provide a wireless...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    and just seconds after finishing this update, I got a new conprog the eMMC now works and mounts! cd /dev /dev # ls blt ram3 tty24 tty50 console ram4 tty25 tty51 cpu_dma_latency ram5 tty26...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    we cleared out a few bugs in the MMC drivers this morning. one more (hopefully the last is being worked on now) the support with Linux 2.6.35 for newer eMMC is lacking so we have to make these modifications Ilya had a fault with this board, it seems to be traceable to his soldering iron being...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    Ilya got his board today, this will speed up programming considerably since we were using my board only which slowed debugging

    First WiFi Loco-Nodes, ready for fabrication/assembly

    tested a bunch of stuff on the new boards, they boot off the eMMC no faults are present in the hardware

    https://www.youtube.com/watch?v=p37ref21X-I&feature=youtu.be The above is an example of the sound engine. We've made a lot of progress on the sound, its going to be killer. The tones will be overwritten by actual sound recordings of the notches and transitions of the real locomotive...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    new boards are on the way these fix IBR booting software compatibility and the audio short so everything should be done for hardware software is progressing with the current boards the Loco-Node file has motor control and FX_LED finished. we added the battery fuel gauge data and battery...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    Motor Control, Consisting, and FX_LED are all now done for Block 0 software We'll be adding in the battery data next. LN0001S-V1.5 will be leaving the factory in the next week, it has all of the hardware glitches cleaned up and some improvements. A black LPI this time too. Here is all I can...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    Here is a video I shot almost two weeks ago, its the motor control file all debugged and ready to go We're just about done the FX LED component of it, I should have it ready this week. Block0 of the software should be ready for release when the new boards arrive in 2 - 3 weeks. Fun times...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    Hello, We've progressed a lot further than the last video posts. The motor control program is in place and now we're tying in the LED's. LN0001S-V1.5 has been ordered. This clears up the hardware snag on the audio and the software issue of incompatible boot ROM with our flash. The new...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    we are 50% away from being able to do V1.5 production, V1.5 will clear up the few issues we had with V1.4 and allow shipments
