I split the design off into two branches, one with SPIFLASH/eMMC and the other with Micro SD Card. The Micro SD Card is being run now, due to the CNY, it will arrive at the end of February
Even though the SPIFLASH/eMMC would be about 99% sure in my mind, the Micro SD Card is 100%. The issue...

the assembly house just got the parts I shipped last month today, one more mod (adding the boot flash) is being done now and I should be able to start the new boards next week
the eMMC is going to be retained, its just not JEDEC compatible for booting. its working awesome though and we now...

MASSIVE hurdle passed today, we have Linux working on my PC and using the eMMC dev kit, we're able to directly modify the eMMC and clone the production software to it. This can then be plugged into our CPU dev kit for testing. This removes ALL file restrictions we had with the manufacturer...

a few updates:
the new development board, eMMC stick, are working happily together, we have include some missing content from the Linux source that was not included in our SDK to wrap up booting, this is in progress
our parts shipment should hit China any day now, V1.6 is ready to run when we...

Ilya has the prime mover sound integrated into the Loco-Node Software. Still some bugs but here is a video:

Ilya has been clipping the sound recordings I made earlier this year of a non turbo 567C prime mover
the software side of this is done as seen with the video I posted where the prime mover was synthetic
these clips will be loaded into RAM and played in place of the previous tones when the...

board design for LN0001S-V1.6 will be finished today, I shipped the final parts out for assembly last night
the board length is the same with the power module addition but the surface components are significantly reduced and the change in layout, programming pads will give a more robust design...

Here is another one from Ilya
What you are seeing is the random generator we built into the sound engine so we can emulate different user experiences with each session. Various sound FX will all employ this. Our FX LED also has it for the Rule 17 so it can simulate different time periods...

all of the parts for the next batch of samples is here, awaiting the new files for the board. some pins were moved around to remove driver issues with SPI0 which effected GPIO on the FX_LED when we went to the eMMC. this has been fixed. we changed the eCompass/6 axis motion sensor so its...

I will have all of the parts for V1.6 on hand next week to ship out for assembly
A few changes have been made based on testing, the board length will be shorter. We also have been able to trouble shoot hardware faults in the audio so they can be signed off with V1.6
Ilya has been progressing...

here is the clip I had printed on Shapeways, I wish this was ready a few weeks ago
it gives a nice mount to place the node inside of the shell but also removes handling issues as the connections for programming can be routed so stress on the connection points is minimized, would have save the...

very huge victory today, we successfully created our own boot code
now we can expand this further
this code enables the board to boot without external connections, its critical to enabling the WiFi antenna and embedding this inside a locomotive

another batch of samples are on the way, no changes except we're putting on a Kingston eMMC which is JDEC5.0 and has a lot better support.
I added some fiber optic to the loco class lights last night. When my Shapeways 0001S Clip arrives, I can put that in the loco and add the pots for the...

I added Dupont Connectors to the Battery/UART/USB connections
The trucks are now reassembled, the truck pickups are able to power the system now, right now its connected to a 15V DC power source and its recharging the Li-PO
The Li-PO will be downsized in the final installation
Right now we're...

eCSD is configured, the find last night solved it for us
we need to test sound and the motion, we can also try a boot test, not sure if we need a boot loader, the development board works without one
-
L
we got the eMMC drivers fully updated to work correctly
I found some info last night on how to change the values in the eCSD, "echo 9 > boot_config" for example so now we're looking into how to set up exactly what we need
we will likely need a UBOOT file but the development board did boot with...

I made these three items to support the locomotive installation
There is a clip that will hold the node, and enable it to be taped to the top of the shell interior
The other two items are "pots". One end is cored for a 0402 LED and the other has an opening for a Fiber Optic strand. I am...
