Hi,we would be interested in integrating the Ara240 into our IMX8MP based solution. Questions are:

• Does the M.2 Ara240 support PCIe Gen3 x1 link negotiation when only lane 0 is connected?
• our current PCIe is A+E key, would this be sufficient to adapt to

Hi Ajith Ali ,

You can only use SPI_B in linux, see:
https://github.com/FSEmbedded/…-mx8ulp.dtsi#L45C1-L45C31

I assume, that you are allready using SPI_B.

SPI_A (FLEXSPI) does not have a linux RPMSG driver and is currently not useable via Linux.
Also…

Hi Team,

Currently, SPI_A is working fine through the client interface with the following configuration from the M33 RPMsg:

spidev0_rpchip: spidev-rpbus-0 {
compatible = "spi_rpbus";
#address-cells = <1>;
#size-cells = <0>;
status = "disabled";

};

Likewise, we…

Hello,

Just to confirm, can the latest Yocto release here be used with the QblissA9r2-V2-LIN board (Qseven standard)?

Thank you.

(Quote from Ajith Ali)

I just noticed that, although UART_C is marked as DBG in the hardware documentation, UART_B is used as DBG in the realtimed firmware.

This means that in Linux, only UART_C and UART_D from RTD can be accessed.

If you also want to use…

Hi Team,

We need some clarification regarding OSM_UART_B, which is routed to the Cortex-M33.
By default, this OSM_UART_B is not enabled in the DTS files, so we have enabled it as shown below:

osm_eth_a: &fec {};
osm_uart_con: &lpuart5 {}; /* A35 console…

Hi @Bharath,

SPI_A (FLEXSPI) and SPI_B (LPSPI) comes from the Cortex-M33 Domain.

SPI_B can be controlled in linux via rpmsg

Thanks.

I would like to clarify the SPI configuration in OSM.
There are two SPI interfaces, SPI-A and SPI-B. Are both interfaces controlled by either the Cortex-M33 or Cortex-A35?

Hi @Bharath,

1. We use currently MCUXpresso SDK 2.16

2. You can find the source code here:
https://github.com/FSEmbedded/realtimed

3. Yocto is unable to generate builds for different architectures as defined in the machine configuration. Therefore, Yocto…
