Review this webpage if you have not done so already:

viewtopic.php?t=4837

to get some good ideas. However, the CPU on the StartKit is not documented and being EOL, doubt that any new information will be made available. Best advice here is to experiment with the more current XCORE-200 series CPU for your needs. At least there are public datasheets for those CPUs.

An an aside, we are working to build some affordable tools / kits for the XMOS line. What would you like to see?

Why is booting from a single SPI flash so important for your daisy chained StartKits? Do recall that the StartKits are based on a dual tile XS1 architecture but one tile is dedicated to be the JTAG tool.

Will study more on how to perform the same task on the XCORE-200 CPU to refresh my memory.

Thank you !
I will try this example at 200 board.

Hi mon2 I have tried example you linked

Did you have any problem compiling example using two 200 board?

Xn file has error

Have not tested it but do not see any complaints.

Can you post your project and the error log after compiling?

I got this result by two custom 200 board

from now I could build the project, but when I command I see like this

so i changed like this

now I could build again tried flashing

Will review in detail later but start with the CPU package referenced in error #3. It is the fbga package and 236 balls.

Later the tqfp package is referenced which is with less pins.

This will impact which pins and links are available.

Compare to the explorer kit CPU package.

Which exact device are you testing? Is this a custom PCB or the XMOS official explorer kits?

The xtag3 has found your 2 CPU devices which is a good start.

I have two custom PCB and one official explorer kits.
I tried this at official to custom and custom to custom

Thank you for reviewing this I will upload the state continually

Which exact CPU part # is onboard your custom design?

Do your custom PCBA work properly in standalone mode?

For example, run the high speed USB hid mouse IP code example from XMOS. This code example will move your mouse pointer in a square pattern till stopped and is great to validate the CPU operation and confirms the USB traffic.

you mean model of cpu?
same model as 200 kit and It works fine standalone

It is designed for use as a network terminal.. ( I didn't make this board, other one made this)

I have not ran any example using usb, but it worked well for network.

Does the chip's USB operation affect the multiboot or link boot method?
Debugging or downloading flash works fine.

Hi. As noted, no direct experience with this daisy chaining of the XMOS CPU devices yet but try the modified XN file.

Does this resolve at least the Error Code # 1 from your earlier post?
