You could try to change the ENET_PHY_ADDRESS in the mpconfigboard.h. It should not be difficult to add drivers for an DP83848 or LAN8720 devices. They all use the same standard set of commands, with just one exception. The ENET_PHY_ADDRESS has to be set to 0 for SomLabs board! Now I can initialize ...

I started to write the boards files for the ARCH_MIX board. For now, I used the following names for the pins: Maybe you could use the names in the form Jn_XX, or you could use just Axx and Bxx and mention somewhere (README.md) A=J3, B=J4. J5 is dedicated to LCD and using it is very hard if you don'...

The I have to check the connections. How long does it take after calling lan.active(True) until the error message pops up? The error occurs in the initialization code , so the lan instance is not even created. Probably the ENET_RESET_PIN and ENET_INT_PIN are wrong (used reset pin, GPIO_AD_B0_09, is...

@loboris: Did you try the Ethernet Port on the VisionSOM-RT module as well? The PHY controller on the base board is the same as on the It reports an error: >>> from network import LAN >>> lan=LAN() Traceback (most recent call last): File "<stdin>", line 1, in <module> OSError: PHY Init failed. >>> ...

We already have a PR open for using the SDRAM for the MP heap. However we did not yet implement code execution from SDRAM. I'm using Robert's repository and MPy heap on SDRAM works without issues. Some info about booting from SDRAM can be found here with some instructions and documentations attache...

Thank you for the feedback. Thanks to all who participated in the work on mimxrt port, of course. It is good to hear you are going to get the Arch Mix board, I think it is quite a good board and the price is very attractive. BTW, do you have any plans to add the option to build the firmware which r...

I've just checked on both boards and using the qspi_nor_flash_config.c from MIMXRT1020_EVK it works!
The file system is mounted on boot (from _boot.py) everything (at least what I've tested) works.

@Roberthh thank you for the help and congratulations on the great work.

I looked into the files, and for the 1050, the qspi_nor_flash_config.c looks wrong. Try to use the file from the MIMXRT1020_EVK at that place. Thanks, I'll try it later today. According to the mex file I have for VisionSOM-RT (1062) module the qspi flash connection is the same as on MIMXRT1020_EVK/...

I dont have the schematic for VisionSOM-RT (1062) module at the moment, but as booting and Flash read operations works, I suppose the connection is the same.

That's interesting. I used that branch just now for flashing. May it be that the flash is connected to a different flexspi port or requires different timings? I've checked the schematics for MIMXRT1050-EVK https://loboris.eu//ArchMix/Screenshot at 2021-10-05 16-31-27.png and Arch-Mix https://lobori...
