TR 03:48 PM Software Development: RE: Interfacing pca9535 with arm using i2c expanders (J5)(i2c5): correction: the extension is J4 Thejas Raj
TR 03:45 PM Software Development: Interfacing pca9535 with arm using i2c expanders (J5)(i2c5): 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... Thejas Raj

Please clone the u-boot and kernel source separately using git. Jonathan Cormier
TR 05:55 AM Software Development: RE: Configuring and editing the pinmux settings for AM57(F) dev kit through dts files.: Hi,
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. Thejas Raj

JC 02:00 PM Software Development: RE: Configuring and editing the pinmux settings for AM57(F) dev kit through dts files.: 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 Jonathan Cormier
JC 01:57 PM 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.

TR 10:30 AM Software Development: Configuring and editing the pinmux settings for AM57(F) dev kit through dts files.: Hi,
We have a yocto source built following the arm development wiki and a working base image.
We are trying to change the pin mux settings some of the peripherals like gpio through the dts files. But cant seem to find anything reg... Thejas Raj

MW 10:47 AM Software Development: RE: Programming FPGA through JTAG and High speed data transfer support: Hi Shankar,
It is a US holiday today, I will add some documentation for programming via JTAG (at least a wiki page) first thing tomorrow.
In the meantime, you should be able to use any AMD / Xilinx approved POD, but you will need a... Michael Williamson
BS 07:03 AM Software Development: Programming FPGA through JTAG and High speed data transfer support: Hello everyone,
We are currently working on a project using the MitySOM-AM57X development board, and we would appreciate some guidance on programming the FPGA via JTAG. Could anyone kindly share the detailed procedure or point us to r... Bhima Shankar

SM 01:24 PM FPGA Development: MitySOM-AM57F communicating to FPGA via PCIe: We are using MitySOM-AM57(F) Development Kit for our development. Are there any examples provided to read and right to the FPGA via PCIe in the default BSP
which you are providing. Shaik Mahaboob Nazeer

BS 06:47 PM PCB Development: RE: I/O voltage levels: Hi Michael,
I would like to thank you for the continued support and prompt assistance you have extended to us.
As we proceed with the next steps, I would appreciate it if you could kindly share the detailed procedure for pr... Bhima Shankar

BS 12:25 PM PCB Development: RE: I/O voltage levels: Hi Michael,
Thank you for your response.
We are initiating FPGA development on the MitySOM-AM57X development board
using Vivado. We are currently seeking the FPGA pin mapping details for the
PCIe interface to the ARM processor. We ... Bhima Shankar

Thank you for your swift and helpful response.
We are planning to use I2C3, I2C4, and I2C5 interfaces of AM57XX in our design.
Kindly correct us if we are mistaken — as we understand from the documentatio... Bhima Shankar
MW 11:41 AM PCB Development: RE: I/O voltage levels: Hello,
You should use level shifters to shift up to 3.3V. Do not pull the I2C pins directly to 3.3V or modify the SOM.
Our Dev Kit schematic uses TCA9803DGKR, but there are several shifters avialable that should work.
Which I... Michael Williamson
BS 10:59 AM PCB Development: I/O voltage levels: In the data sheet of MITY-SOM_AM57F SOM board page 4, it is mentioned that the AM57XX MFIOs are operating at 1.8V level except mmc1 pins. We have an I2C connections that goes to AM57XX processor, we need the voltage levels of the I2C pin... Bhima Shankar
