Crash on initialize UART #37

Closed key closed 5 years ago

key commented 5 years ago

Hello

I tested m5cluod firmware with micropython. The device crashed when initializing UART. Reproduce this issue in different firmware that are m5cloud-psram-20180419-v0.3.9.bin and m5cloud-psram-20180516-v0.4.0.bin.

Hardware: M5Stack Fire GPS: M5Stack GPS module

I have investigated this issue. M5Stack Fire will crash when uses PSRAM with GPS module. That was conflicts PIN GPIO 16 and 17.

It's NOT firmware issue, sorry!
