armv7a7-imx6ull-evk: can't communicate with psh

Open damianloew opened this issue 2 years ago • 5 comments

For the latest commit in phoenix-rtos-project (d464da30ea18b1c79764fa841f91a23b261ea070). When uploading image to ram as required (https://github.com/phoenix-rtos/phoenix-rtos-doc/blob/master/quickstart/armv7a7-imx6ull.md) it seems like uart read does not work. There are no characters printed when entering them on the keyboard. Buliding with the following command: TARGET=armv7a7-imx6ull-evk ./phoenix-rtos-build/build.sh clean core fs image project Screenshot from 2022-06-13 11-20-21

It's the following change (not sure why was it applied): Screenshot from 2022-06-13 11-45-22

now RX doesn't work if the device isn't open (which is the correct behavior and saves some cpu clocks). Please verify if psh correctly opens the tty device file (maybe it's a problem with psh input params)

After setting this macro console works, but very 'slowly' Screenshot from 2022-06-21 16-27-45

It seems to no longer occur, when using b64d8e617b5e68b6df4d6781a8ed1328a5ed1783 phoenix-rtos-project revision.
