SYSCONFIG: sysconfig crashing when trying to add a new MCSPI device

Part Number: SYSCONFIG

CCS

Version: 12.5.0.202309161830
Build id: N202309161830

Sys Config 1.18.0.3266

We are using the SPI in 3 wire mode and bit bashing GPIO for the chip select signals

SPI1 already configured and working correctly using bit bashed GPIO for chip selects. Note that GPIO pins used are the same ones that could be assigned to the SPI in 4 wire mode (SPI1_CS0/CS1/CS2/CS3, pins B14/D14/D16/E16 respectively)

At the same time as configuring the GPIO for SPI1 I configured the GPIO for SPI0 (SPI0_CS0/CS1, pins D12 and C13)

After completion of testing SPI1 I tried to add SPI0 in syscfg.

It crashed

I checked for and loaded available updates automatically.

The problem persisted

I remembered that when adding a MCSPI it defaults to 4 wire mode

This prompted me to remove the GPIO pin assignments for SPI0_CS0/CS1

I could then add SPI0 without syscfg crashing. Set SPI0 to 3 wire mode, reassigned GPIO and bob's your uncle (metaphorically in this case)

Hi Steve,

Could you clarify what device you are using so your question can be assigned to the appropriate expert?

Thanks!

Hi Asha,

We are using AM64x. The syscfg file we are modifying is based off of the am64x-sk_r5ffs0-0 hello world example.

Cheers

Steve

Hi Steve,

Thank you for the clarification! It should be assigned to the correct engineer on our AM64x Sitara team shortly.

Best,

Asha

Hello Steve,

It would be helpful if you could forward me the project file where you were encountering problem while adding another SPI peripheral via SysConfig.

I will make sure my setup replicates the versions you have mentioned in the question.

I would need to replicate this at my end for me to understand why the problem persists.

Looking forward to your project file.

Thanks,

Vaibhav

Hi Vailbhav,

How is the best way of getting the file to you? Attaching it to this reply does not seem to be allowed.

Cheers

Hi Vaibhav,

Were you able to recreate the issues from the project file? Or do you need something else?

Cheers

Hi Steve,

I think it might be a problem due to conflict of pinmuxing.

I am still looking into this.

Please expect responses by tomorrow.

On a side note, can you please send me the project file which includes the sysconfig file, the main file and so on instead of the sysconfig standalone.

It will be much easier for me to debug. I am also assuming you are using MCU PLUS SDK AM64x 9.1

Thanks for your patience.

Regards,

Vaibhav

I have resent the original email dated 23/01/2024, please confirm you receive it and the zip contains everything you require.

Hi,

I checked the older email dated 1/17/2024, as I have not received any email from you on 23/01/2024.

I coped the sysconfig file contents and added it to am64x mcu sdk 9.0 version.

Post this, I opened the GUI and added MCSPI0, for which I see error popping up, stating the conflict in CS assignment.

Upon reviewing the GPIO section in SysConfig, the conflict happens because for MCSPI0 the available pins are D12, C13, B16 and A16, and GPIO has all of these already added.

S3_RTS -> A16

S3_CTS -> B16

SPI0_CS0_IO_BOARD -> D12

SPI0_CS1_LED_BOARD -> C13

Hence this is expected and to overcome this, you have to remove the particular assignment from GPIO and use it for MCSPI0 accordingly.

Hope this helps.

Thanks,

Vaibhav
