DRA821U: Support Required: MCU SPI1 Issues with SRAM and TPM on DRA821U

Subashini N

Part Number: DRA821U
Other Parts Discussed in Thread: DRA821, SYSCONFIG, TPS6594-Q1

Dear Team,

We have connected SRAM (23A512-I/SN) and TPM (ATTPM20P-H6MA1-10) to the MCU SPI1 interface as slave devices on the DRA821U platform and added the corresponding DTSI entries for both devices. In our configuration, SRAM is connected to CS0 and TPM is connected to CS3.

During boot, we observe a timeout error from the TPM driver:

tpm_tis_spi: probe of spi0.3 failed with error -110.

To debug this, we probed the chip select (CS) pin of the SPI controller. We noticed that when the TPM driver is loading, the CS pin does not toggle low. Throughout the entire boot sequence—from U-Boot to kernel—the CS line remains high (as observed on CRO) but the SRAM CS pin is going to low when the SRAM's driver is loading. Also, the clock is generating properly (12.5 MHz).

Additionally, we are facing an issue with the SRAM device where write operations to the memory block are not functioning as expected.

Could you please guide us on how to resolve these issues? Also, is there any limitation or special consideration for using multiple chip select lines on MCU SPI?

Hi Subashini,

I recommend using the sysconfig tool for pinmuxing, if not already: https://www.ti.com/tool/SYSCONFIG

Alternatively, you may reference the datasheet (https://www.ti.com/lit/ds/symlink/dra821u.pdf). I see that the WKUP_GPIO0_5 should be muxed to 2 for the CS3.

Regards,

Takuma

Hi Takuma,

We are configuring SPI SRAM and a TPM module in the DRA821U device, but it seems both are not working as expected. As I mentioned in the previous thread, the SRAM having the r/w issues, so for isolating the issues, we did a SPI Loopback test by shorting MISO & MOSI hardware-wise & tested a loopback with spidev_test utility, but the data transmitting through TX is not getting back on Rx. Please check and let you know your observations.

All the SoC-side configurations & required test logs are attached with this.

Hi Subashini,

Please reference FAQ: [FAQ] Troubleshoot Guide for McSPI within Linux: J784S4/AM6x/TDA4x/DRA8x

May be issue with the internal connection for mcu_spi1

Hi Takuma,

As per the reference you shared, I have added the below DTSi entry for disconnecting the MCU_SPI1 and MCU_SPI3 interconnection in k3-j7200-mcu-wakeup.dtsi file but when checking the register value in the kernel, it shows 0 only. Did I miss anything? Could you please help us to fix this?

spi1_linkdis: mux-controller@4060 {
compatible = "reg-mux";
reg = <0x4060 0x4>;
#mux-control-cells = <1>;
mux-reg-masks = <0x0 0x1>;
idle-states = <1>;
};

Thanks and Regards,

Hi Subashini,

That should work. Is the spi1_linkdis node defined under mcu_conf node?

Takuma

Hi Takuma,

I have added spi1_linkdis under mcu_conf, and now the register value has changed to 0x01. As per your previous reference, I updated J721E_WKUP_IOPAD(0x64, PIN_OUTPUT, 0) to J721E_WKUP_IOPAD(0x64, PIN_OUTPUT, 2)

After this change, while loading the driver, the chip select line transitions from low to high instead of high to low. I have not changed the SPI controller mode, and it is still operating in Mode 0.

Additionally, the TPM is throwing a timeout error.

Could you please guide us on how to resolve this issue?

Hi Subashini,

Can you share logs? And is the sram now working, and only TPM is failing?

Regards,

Takuma

Hi Takuma,

After disconnecting MCU SPI1 and MCU SPI3, the SRAM started working. We then removed the SRAM from the MCU SPI 1 and kept only the TPM connected as CS3. While loading the driver, the clock is running at 12.5 MHz, but the CS line is toggling from low to high instead of high to low.

Please find the attached dmesg log for your reference.

Hi Subashini,

Subashini N said:
As per your previous reference, I updated J721E_WKUP_IOPAD(0x64, PIN_OUTPUT, 0) to J721E_WKUP_IOPAD(0x64, PIN_OUTPUT, 2)

Instead of 0x64, it should be 0x6C for the TPM CS, that should have the muxing for 2. The 0x64 for CS0 is fine to leave at 0.

I would recommend using the sysconfig tool for pinmuxing, or reviewing the datasheet.

Hi Takuma,

I have tried configuring reset-gpios = <&main_gpio0 51 GPIO_ACTIVE_LOW>; However, the chip select line is still toggling from low to high.

Could you please let me know if there are any limitations with MCU SPI1? We observed that CS0 is working properly, but CS3 appears to have a chip select polarity inversion issue.

Also, could you confirm whether MCU SPI1 supports multiple slave devices connected across different chip select lines?

Thanks and Regards,

Hi Takuma,

I probed the TPM reset pin and observed that it stays low throughout the entire boot process. However, the expected behavior is that the reset line should remain high when the board powers on, and during TPM driver loading it should toggle from high to low.

To address this, I configured the TPM reset GPIO as high using the gpio-hog property in the DTSI. After this change, the reset line goes high during TPM driver loading, but it remains high continuously and does not toggle as expected.

I also tried changing the GPIO value through the kernel sysfs interface and probed the signal using the CRO. On the CRO, the GPIO value is toggling correctly, but in the kernel it still shows the value as 0.

Is there any workaround or recommended approach to make the GPIO toggle properly during runtime?

Thanks and Regards,
Subashini

Hi Subashini,

Issue is now most likely with the specific driver for TPM then. You have a reset-gpio defined in devicetree, but I do not see reset-gpio property in the yaml Documentation of the kernel code.

Please reference: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml?h=ti-linux-6.12.y

There looks to be a "lpcpd-gpios" property instead, which sounds the closest to a reset GPIO pin. In any case, would recommend looking through the TPM device driver as a next step, since McSPI interface itself looks to be functioning with the Microchip SRAM device.

Regards,

Takuma

Hi Takuma,

After updating the reset property as per your reference, TPM is working, but I am getting the below kernel crash related to an interrupt while testing the TPM. In my dtsi under the TPM node, I didn't give an interrupt property because the TPM device doesn't have an interrupt. Could you please help us to resolve this crash issue?

Hi Subashini,

I think issue has moved more towards debugging TPM device. Disclaimer that our knowledge for this device will be limited.

Does the TPM device have a physical interrupt pin that is connected on your system?

Hi Takuma,

TPM doesn't have an interrupt; only the MCU SPI1 has an interrupt as shown below.

reg = <0x00 0x040310000 0x00 0x400>;
interrupts = <GIC_SPI 849 IRQ_TYPE_LEVEL_HIGH>;

Hi Subashini,

I recommend reading the datasheet of the device. The TPM datasheet looks to have an extra IRQ pin that is not present for the SRAM that you are using:

Since the SRAM is working, I suspect the issue is specific to TPM, so please review the TPM datasheet and software to see if there is anything that stands out.

Regards,

Takuma

Hi Takuma,

As per the TPM device's datasheet, we are not using the interrupt pin; also, it is connected to a 4.7K-ohm resistor.

Hi Subashini,

I reviewed the dts again. Looks like this line changed pinmuxing in the latest tests:

J721E_WKUP_IOPAD(0x60, PIN_INPUT, 1) /* (D14) WKUP_GPIO0_2.MCU_SPI1_D1 */

Can you change this back to 0 instead of 1?

Hi Takuma,

I changed the input pin configuration to J721E_WKUP_IOPAD(0x60, PIN_INPUT, 0), but the crash is still observed. Upon checking the interrupts, it appears that the PMIC interrupt is causing the crash while testing the TPM driver. Below are the attached PMIC DTSI entries and the interrupt list.

Hi Subashini,

Good find. Although, strange the PMIC is acting up. Does the PMIC interrupt only come when the TPM is tested? Or does the interrupt trigger regardless of whether TPM is initialized or not?

And is it possible to experimentally take out the PMIC interrupts to see if that interrupt is the cause of the issue?

Regards,

Takuma

Hi Takuma,

Yes, the PMIC interrupt is occurring only when the TPM is tested. Before TPM initialization, we did not observe any crash. The crash happens only after the TPM driver initialization.

While checking further, I found that the PMIC controller was configured as:

interrupt-parent = <&wkup_gpio0>;

However, it should be configured to use main_gpio. Also, the interrupt pinmux configuration needs to be updated as shown below since the interrupt is connected to EXTINTn.GPIO0_0:

J721E_IOPAD(0x0, PIN_INPUT, 7) /* (U6) EXTINTn.GPIO0_0 */

After updating these configurations, the crash is no longer observed.

Thank you for your support throughout this case. You may proceed to close this case.

Thanks and Regards,

Subashini
