Running system on armv7m7-imxrt106x (NXP i.MX RT106x)

This version is designated for NXP i.MX RT106x processors with ARM Cortex-M7 core. To launch this version the final disk image and loader image should be downloaded. The images are created as the final artifact of phoenix-rtos-project building and are located in _boot directory. The disk image consist of bootloader (plo), kernel, UART driver (tty), dummyfs filesystem server (RAM disk) and psh (shell). The necessary tools to carry out the flashing process are located in _boot directory as well.

Default configuration of peripherals allows to run Phoenix-RTOS on i. MX RT1064 - EVK: https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/mimxrt1064-evk-i-mx-rt1064-evaluation-kit:MIMXRT1064-EVK

Running loader (plo) using SDP

In order to flash the disk image to the board, the bootlader (plo) image located in _boot directory should be uploaded to the RAM memory using psu (Phoenix Serial Uploader) via SDP (Serial Download Protocol).

NOTE: i. MX RT1064 should be set in Serial Download mode. Set appropriate configuration of SW7 switch on i. MX RT1064 - EVK.

Run psu as follow:

$ sudo ./psu plo-ram-armv7m7-imxrt106x.sdp

The plo user interface should appear on UART1 - connector J41 on i. MX RT1064 - EVK. The default baudrate is set to 115200 bps.

To get the available bootloader command list please type help.

Copying flash image using PHFS (phoenixd)

To flash the disk image, the another serial connection has to be established. For this purpose the UART3 located on arduino interface is used. To share disk image to the bootloader, phoenixd has to be launched with the following arguments (choose suitable ttyUSBx device):

$ sudo ./phoenixd -k ../_build/armv7m7-imxrt106x/prog/phoenix-armv7m7-imxrt106x.elf -p /dev/ttyUSBx -b 115200 -s .

To start copying file, write following command:

(plo)% copy com1 phoenix-armv7m7-imxrt106x.disk flash0 0 0

Booting Phoenix-RTOS from internal Flash

To launch Phoenix-RTOS from flash memory, change SW7 switch to Internal Flash mode and restart the board.

If everything has gone correctly, the bootloader should launch Phoenix-RTOS with default configuration and psh shell command prompt will appear in the terminal.

Using Phoenix-RTOS
