### Expected behavior
I wanted to port MicroTVM as easily as possible on a cortex-m4 (float)-based stm32g474 to test the inference speed of the MCU that was not optimized. Simplest HelloWorld model…

### Describe the bug
This bug is hard to reproduce since it depends on how many package are compiled in parallel ( I compile with -v256 ) and it only occurs once on 10.
Compilation ends with som…

Hi,
We are trying to migrate golden-gate to a Cotex-M4 chip (GR5515, this chip is very cheap). I notice there are source code for NRF52840 in golden-gate/platform/mynewt/apps/gg-tool/apps/gg_centr…
