GeneralSwitching to STM32 Arm Cortex Ms - what a mess Pin

I've been deploying ESP32s professionally, and I'm getting crap for it from engineers, which concerns me.

I've also heard they are hard to get certified.

I've also had some bad experiences with half-baked hardware implementations in certain areas of the ESP32.

It's time for me to switch to ARM based devices. I don't want to. The ESP32 is cheap to develop against, and I've spent a lot of time learning its intricacies and quirks.

I tried to get an ARM Cortex A based SBC to run xboot so I could use it without an OS and eliminate boot times but I've had no luck.

I hope the STM32s go better, but the black pill and nucleo boards I had were terrible to develop against.

The problem with the STM32s I've found is they just don't have enough SRAM or flash.

I ordered this yesterday:

Amazon.com: STM32F3DISCOVERY ST STM32F303VCT6 STM32 F3 ARM Cortex-M4 MCU Discovery Evaluation Development Board kit Embedded ST-Link/V2 debugger @XYGStudy : Electronics[^]

It's only got 48kB of RAM. To decompress a JPG or PNG takes at least 32kB due to the huffman algorithm.

I wish I could find a package with 512kB of flash and at least 192kB of SRAM. That I could work with.

I still hate developing against these things but that would be a start. Problem is I haven't found anything like that except the Teensy 4.1, which is great, but I can't source their NXP chip. The lead times are crazy.

I need a STM32 solution.

Every time I try to make this change I run into walls and I'm worried that my little two to four person team just doesn't have the resources for this. Frown | :(

Edit: Figures. I've been looking around and once I posted this I found something promising: NUCLEO-H745ZI-Q

It's based on ST32H727 which looks to be an upgrade from the ESP32 in terms of capabilities, so that's a win.

I hope this works.
