I'm currently developping a Raspberry pi HAT. The Raspberry pi HAT must contain a EEPROM with several information in it. This information will be read at boot time in order to configure the Raspberry pi (GPIO port direction, name of the card, vendor Id, ...). Moreover the information are available (after reboot) in the folder /proc/device-tree/hat.
The fact that I must reboot each time is an incredible loss of time for my test. So my question is the following: Is that possible to reload the device tree and have access to the folder /proc/device-tree/hat without rebooting?
Thanks in advance!
