Hi;
there is a global shortage of STM32 processors on the market. I've seen
STM32F767 selling for 480U$.
Has anybody tried Gigadevice processors? They claim to be STM
replacements. I've got a design ready for a 144 pin STM32 (either F767
or F427/429), and it seems that the GD32F427 are replacements for those
that you can actually buy in quantities for a normal price (8.74 U$ for
an GD32F427ZGT6)

Does it run NuttX?
