The driver is progressing fine. Soon the keypad will be driven by my open source driver.
Digging through my documentation I figured a way to eventually upgrade the operating system on every controller (this includes the splash screen) from within Linux.
This is still not yet researched very well and would require a lot of work to actually perform well and reliable.
This discovery also led to the creation of the flash image dumper which copies the contents of the NAND memory chip to the attached USB stick.
Since I know that 4-axis controllers, 3-axis controllers and the RATTM model have different NAND contents, I need your help to get the software working on every system alike.
Please, if that person had 5 minutes, could someone with a 4-axis and someone with a RATTM system please run the image dumper attached to this post and provide me with the resulting nand.img file?
This would really help speed up development and check the differences between the different models.
The attached utility should not harm your controller and will not leave any permanent modifications.
After running it, it is enough to delete the ndutils folder and the startup.done file from the USB stick to free up the few KB that the dumper needs.
To execute the utility, simply extract the zip file onto an USB stick and reboot the controller with the stick inserted. The controller will now guide you through the automated process.
