Ok, so the Archmix wiki talks about how to connect to the RT-Thread shell on the board with a serial adapter, and how to test micropython.
I’m searching for info about the board, low level basic info about bootloaders and boot initialization, and board specific details that general NXP docs won’t get me.
I found out that I will need
arm-none-eabi gnu toolchain with gcc
(which one you need depends upon your “host” machine’s processor, the “target” is a 32bit armv7 for the RT1052 processor with M7 core)
nxp’s latest mfgcfg utility called ‘uuu’ that you can get from https://github.com/NXPmicro/mfgtools
I still don’t know how it will work to upload, as I read more details from NXP about their 2-stage bootloading, and their flexSPI and this strange firmware deluxe they seem to have for loading code.
There is very little information on the internet on this very capable board and how to use it. The NXP docs on their own demo board are useful, but I wonder about pinout differences and more. It’s a Seeed studio board, so let’s get some culture and chatter going on about this board here!.. there’s only 2 posts in the entire forum on this entire board.
As I slowly figure my way through the GCC simple way to develop with this board, I’ll post info as I learn it.
it’s a realtime processor, if micropython and rt-thread are really the canonical way to interact with this, then let’s bring up a peripheral with this system. has anyone done anything with this board yet?
I’ll be trying to bring up the SAI with an audio codec.
I intend to use the NXP SDK and try to use their driver bare-metal to run audio pass-through.
it might take me some time, as I try to learn more about how to load binaries to the device…
