Hi @slorquet the H7 drivers derives from F7, so I should starting comparing the Reference Manual from both chips to spot some differences. I know a company here in Brazil...

Hi @slorquet sorry my delay, I was really busy last week preparing the NuttX Workshop... I asked them about it and they suggest you to try reseting git nuttx repo...

@SrivamsiMalladi you need to define which UART will be your serial console, you do it on menuconfig (**$ make menuconfig**) then if you need UART0 as serial console your need...

Please look the inside esp32_serial.c file, since CONFIG_UART0_SERIAL_CONSOLE is defined, the only way to CONSOLE_DEV be undefined is if USE_SERIALDRIVER is undefined. And this symbol is defined inside arch/xtensa/src/common/xtensa.h Probably...

@SrivamsiMalladi are you using the ```esp32-devkitc``` board or did you create your own board based on it? Seems like something is mis-defined/mis-configured. Try to figure-out if USE_SERIALDRIVER is undefined and...

@SrivamsiMalladi you don't need to create a esp32_uart_driver.c because the uart driver is already created inside arch/xtensa/! All you need to do it use the device from userspace. So, your...

Did you enable "[*] UART 1" in the menuconfig? Otherwise /dev/ttyS1 will not be created!

I suggest you to start with the basics, first clear everything: ``` $ make distclean ``` Then configure the board: ``` $ ./tools/configure.sh esp32-devkitc:nsh ``` Now compile/flash it: ``` $...

I don't understand what exactly you are trying to do. If the code is creating /dev/ttyS0 and /dev/ttyS1 it means everything is correct. Why are you calling uart_setup(&CONSOLE_DEV)? I think...

@masayuki2009 @jerpelea any idea?
