HI TI experts,

We are currently designing a custom board leveraging TI SK collaterals.

We have a tight project timeline Is there some guidelines that i could follow to do a self-review of the custom board schematics before i build the boards.

Hi Expert,

My customer Motovis report an issue about ethernet link down issue, customer have catch the MDIO using the Logic analysis, they find there is some difference between B version (SR1.1) and C version (SR2.0). customer are using the same SW, and they actually only send the clause 22 protocol, and they can see only clause 22 in SR1.1 device, but in SR2.0, there is a lot of clause 45 you can see below screen shot. this difference cause customer line down, all SR2.0 board will link down so that the ethernet will work abnormal. need you help for this issue urgently; do you know any SW change need to be apply for this MDIO in GP device? or any difference between this? customer confirm this issue is related silicon version.

SDK version: SDK 8.4, GP Device

SR1.1:

SR2.0

Hi Ti Experts,

I am designing a custom board for the AM6254 SoC and trying to connect an SPI peripheral to the AM6254 SPI interface.

I intend to use MCU_SPI1 Channel but I am not sure which one is MISO and MOSI between MCU_SPI1_D0 and MCU_SPI1_D1.

Kindly help me identify which one is which.

Looking forward to your response. Thank you.

Regards,

Paul.

Hi TI Experts,

Customer is working on TDA4AP SDK10.0. They are using SPL boot.

They want to change the De-emphasis to be -3.5dB for PCIe0 for 5.0GT/s to minimize reflection. Please see the below description for details.

We have also found the corresponding setting below.

Could you please suggest coding how could we change De-emphasis to be -3.5dB for PCIe0 ?

Many Thanks,

Kevin

I am using a processor with a DM R5F (AM62x, AM62Ax, AM62Px). I am using SDK 9.2.1 or SDK 10.0. The Device Manager (RM) R5F core is listed in the Linux devicetree, so Linux should use the remoteproc driver to attach to the DM R5F during Linux boot time, and initialize RPMsg communication with the DM R5F [1] [2]. However, the Linux remoteproc driver is failing with error -19. What is going on?

Here is an example of a "working" attach to the DM R5F core:

[    6.569096] platform 78000000.r5f: R5F core may have been powered on by a different host, programmed state (0) != actual state (1)
[    6.572660] platform 78000000.r5f: configured R5F for IPC-only mode
[    6.573291] platform 78000000.r5f: assigned reserved memory node r5f-dma-memory@9da00000
[    6.573941] remoteproc remoteproc3: 78000000.r5f is available
[    6.574088] remoteproc remoteproc3: attaching to 78000000.r5f
[    6.589108] platform 78000000.r5f: R5F core initialized in IPC-only mode
[    6.589191] rproc-virtio rproc-virtio.5.auto: assigned reserved memory node r5f-dma-memory@9da00000
[    6.589483] rproc-virtio rproc-virtio.5.auto: registered virtio1 (type 7)
[    6.589504] remoteproc remoteproc3: remote processor 78000000.r5f is now attached

And here is an example of a failing case:

[    6.670963] platform 78000000.r5f: ti-sci processor request failed: -19
[    6.671050] platform 78000000.r5f: ti_sci_proc_request failed, ret = -19
[    6.674274] k3_r5_rproc bus@f0000:bus@b00000:r5fss@78000000: k3_r5_core_of_init failed, ret = -19
[    6.674301] k3_r5_rproc bus@f0000:bus@b00000:r5fss@78000000: k3_r5_cluster_of_init failed, ret = -19

Additional notes:

[1] The DM R5F core starts running earlier in the boot process than Linux. For most remote cores (i.e., non-Linux cores), the Linux remoteproc driver both initializes the core, and sets up the infrastructure to enable RPMsg communication with the remote core. However, since the DM R5F core is already running, the Linux remoteproc driver simply "attaches" to the already-running DM R5F, and initializes the RPMsg infrastructure. For more information about booting & disabling processor cores, refer to the Multicore module of the associated processor academy:

[2] If RPMsg communication is not used with the DM R5F, and Linux does not interact with the DM R5F code during runtime, then the remoteproc driver does not need to attach to the DM R5F in the first place. However, keep in mind that the DM R5F's DDR memory allocations should ALWAYS be reserved in the Linux devicetree file, in order to prevent Linux from overwriting the DM R5F's data.

Hi,

I have a Starter Kit (SK) Edge AI device with a CSI sensor connected and would like to stream to my display. I have enabled the sensor by following the steps outlined in section 2.1 "Hardware Setup" and have validated functionality by running one of the out of box demos as outlined in section 3. "Edge AI sample apps". How to preview camera and stream the sensor output without any DL tasks in my pipeline?
