imxrt1020-module's Issues

Wish: having SWO pin routed to the SWD/JTAG debug header

SWO is great for pulling data (trace, print text, ...) from the core, but requires the SWO pin routed to the header.
Concern: The SWO pin is shared with ENET_CRS_DV (pin 97, GPIO_AD_B0_11) and cannot route to pinheader without signal degradation.

4x2 vs 5x2 SWD/JTAG debug header

Thank you for that really great project!
Just a question: was there a special reason to use a 4x2 (instead the standard 5x2) for J47 except to possibly save some space?

Best regards,
Erich

Find name for the board

The imxrt1020 module is too much generic. Need a new name.

The tentative name was CIAA-7 (in spanish "computadora industrial abierta argentina") but due the international contribution this require other name convention (and the CIAA name is creepy in all form 😆 )

Some sugestions:

• imxrt1020-board 👍
• imx-rt module
• iMX-SBC
• Another obscure name referring particular situation, country or ideology)
• Jon Connour Board or other altered cinema/comic/variete character name
• Your sugesstion
• RT1020-[A-Z]* with greek/roman good names 👍

Migrate from 5/5mils tracks to 6/6mils

Investigate the migration of design to more cheap 6/6mils tech and 0.3mm hole.

Need:

• Simulation of SDRAM route: 5mil/7mil to 6mil/7mil is not significative change on signal integrity
• Re-estimation of size: The global size of the board remain unchange
• Simulation of hot-speed signals like usb HS, ETH and SDRAM reflections

Maybe not for first prototype.

Producing a few PCB's, ready to go?

I have ordered samples, and I want to go ahead and produce a few PCB's for first prototypes.
I just want to check and ask if this is a good idea now or I better should wait if some pending changes are up in the pipe?
