New Contributor[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-entry of the mentioned component only contains one interrupt in the generated .dtso-file.
To be exact, the dts-entry correctly contains 2 interrupts in the interrupt-names-array, but not in the actual interrupts-array.
I would expect something like this: "interrupts = <0 41 1>, <0 42 1>;"
(40 is the base-number -> 41 corresponds to irq-number 1, 42 corresponds to irq-number 2...)
The fact that the interrupt-names-array is correct indicates that the interrupts are exported correctly.
Best regards,
Jakob

Hi
I believe that you are using the sopc2dts converter to generate the device tree file from the sopc file info?
Sorry to say that we have discontinued the sopc2dts converter. The device tree would need to be created or edited base on our GSRD package.

jakobjung10Hi @JingyangTeh_Altera !
Sorry for replying late.
Can you assist in generating the dtso-file with the mentioned GSRD-package?

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.

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However, you mentioned that the sopc2dts-converter is outdated.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...)

Hi
For the current method, the device tree of the devkit have been uploaded to the uboot branch below:
In the device tree all the peripheral node have been created base on the Cyclone5 dev kit.

Hi
For the GSRD device tree could be found under the github link below:
The device tree created is based on the CycloneV dev kit. You could enable and disable any node t
hat is available base on your custom board.
