[BUG]: Platform-Designer generates invalid .dtso-file (multiple interrupts not possible)

Hi, I am generating a system in platform-designer with multiple custom components. I have one component with multiple interrupts (2 interrupts, to be more precise...). However, the device-tree-ent...

Hi


Yeah Sure.

There are plenty of how to in editing the device tree online.

For the interrupt cell below are the explaination on the entery:

  • The 1st cell is the interrupt type: 0 for SPI interrupts, 1 for PPI interrupts.
  • The 2nd cell contains the interrupt number for the interrupt type.

SPI interrupts are in the range [0-987], PPI interrupts are in the range [0-15]

  • The 3rd cell is the flags, encoded as follows:
  • bits[3:0] trigger type and level flags.
  • 1 = low-to-high edge triggered
  • 2 = high-to-low edge triggered
  • 4 = active high level-sensitive
  • 8 = active low level-sensitive
  • bits[15:8] PPI interrupt cpu mask.



Regards

Jingyang, Teh

Hi @JingyangTeh_Altera ,

I am aware of the explanations for the different entries.

My temporary solution was to manually edit the device-tree-file.


However, you mentioned that the sopc2dts-converter is outdated.
So what is the modern way of automatically generating a .dtso-file? (you mentioned GSRD-package...)

BR,
