Analysis of the use of PX2 development board Linux development tools, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Instructions for the use of Linux development tools

First, run the upgrade_tool program (sudo is required)

Enter devNo to select the device, press R to search again, and press Q to exit

2. After selecting the equipment, the main interface is as follows:

On the left is the function description, and on the right is the command syntax. Upgrade related operations are all in upgrade

Under the command list, you can enter H to view if you forget the command syntax, and enter it by clearing the screen.

CS, press Q.

CD command: select a device. When the command contains a device restart operation, you need to re-select the device, and when you change the operating device, you need to re-select the device.

The SD command: msc switches to rockusb upgrade mode. When the handover is successful, you need to reselect the device

UF command: upgrade the full update.img firmware and reselect the device when the execution is successful

UL command: upgrade the loader function. You need to reselect the device after successful execution.

DI command: download a separate image image to a specified sector, such as upgrading kernel.img or system.img can use this function directly.

For example, download kernel.img:DI-k

Kernel.img parameter / / if you have previously downloaded parameter through di, you do not have to specify the final parameter parameter when downloading kernel.img

DB command: download boot. In maskrom state, you can use this function to let maskrom devices communicate with Rockusb protocol.

EF command: erase the entire nand flash

LF command: keep the area behind the block in low space and use it only in loader mode

Note: DI, UF, UL, RD, SD, EF, LF, DB and RD commands support command line calls, for example: sudo. / upgrade_tool uf update.img

Note: starting from version 1.13, the DI command can be used to download multiple partitions at a time, such as downloading kernel and system.

Di-kmam murs kernel.img,system.img

If the default path is pre-set in the config.ini file, the command can be simplified to:

Di-kmam murs
