- Hi Debashis,
I think you are correct.
I only have seen TI mentioning supporting CODESYS for ethernet master operations an the AM62x family. For slave you'd likely have to run the R5F and I don't think you can share the switch with... - RD 10:55 AM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Issue with Native EtherCAT Driver Installation on AM62A with IGH Stack
- Hi Experts,
Both interfaces are linked to the same bus address (8000000.ethernet), which I understand represents a single CPSW Ethernet controller.
To illustrate the architecture:

First please note that the R6/T9 pins will be 1.8V logic level. If your device is 3.3V logic level you will need a voltage translator similar to U5 on the devkit.

- Hi,
So we were able to interface i2c5 of the evk with our pca 9535 i2c device.
As of now we also require i2c4 of the evk/som whose scl and sda are currently muxed to gpio7_3 (R6) and gpio7_4 (T9) respectively.
Can you give us the...

- TR 08:55 AM MitySOM-AM57X Software Development: RE: Interfacing pca9535 with arm using i2c expanders (J5)(i2c5)
- Sorry for the late reply.
We were able to interface the pca9535 after adding the respective nodes for it in the i2c5 bus configuration in the am57xx-mitysom-baseboard.dts file.
Will update if anything else comes up.
Thank you

What does this mean? How is data coming from the pca9535 if you cannot talk to it?

- Hello,
We are trying to interface external pca9535 with the evk via the i2c5 bus. We'll be using the J5 extension on the board to do so.
As far as I know, 0x21 is the memory address that is supposed to be used by pca9535 but i2cdet...

Thank you for your reply.
And can you give me the path to the u-boot device tree in the yocto environment. The boards/cl directory mentioned in the u-boot wiki that you just provided, especially. - RD 06:40 AM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Enquiry about mcu_safety_error pin

Thank you for your response.
We are working with the SDL (Safety Diagnostic Library), and as part of this, we have enabled DCC, ECC, and MCRC as per our requirements. Now, we are moving on to BIST (PBIST/LBIST).
As we u...

- Note if you are developing a custom board, we'd be happy to do a schematic/layout review as well. Those can be emailed to info@criticallink.com
- JC 01:57 PM MitySOM-AM57X Software Development: RE: Configuring and editing the pinmux settings for AM57(F) dev kit through dts files.
- Unfortunately TI's guidance at least for SDK 6, is that the majority of pinmuxing must be done in u-boot while the IO's are in isolation mode... Setting up the pinmux in u-boot is covered in this following wiki page.

- Hello,
The MCU_ERRORn signal is not connected to the PMIC. It is pulled low on the board via a 4.7K resistor.

Question 1. For the MitySOM AM62A, is the pin MCU_SAFETY_ERRORn connected to the PMIC ?
