Hi Hanmant,

Can you please check if you are using proper UART port in custom board according to 2019 u-boot version?

Regards,

Anil

Hi Anil,

Thank you for responding.

What do you mean by Uart Port?

Where to check that 

I already using 2016 version that works fine on my custom board.

Check this configuration.

Can you tell me what is wrong in this .

Can you please suggest me where to change in uboot source code

Anil Dali  any update on this.

Hi Hanmant,

Uart port means, in new 2019 u-boot version, we need to check whether we are configuring the UART3_txd and UART3_rxd pins for console log.

Can you please compare the files you shared with the older version(2016 u-boot source file)

am57xx-idk-common.dtsi,  Mux.h ?

Regards,

Anil

Anil Dali ,

am57xx-idk-common.dtsi,  Mux.h 

Please check shared configuration. Those pin configuration same as what i used in 2016 u-boot version.

Can please these configuration is correct or not

&dra7_pmx_core {
u-boot,dm-pre-reloc; /* ← THIS is what's missing */

uart3_pins_default: uart3_pins_default {
u-boot,dm-pre-reloc; /* ← AND THIS */
pinctrl-single,pins =
DRA7XX_CORE_IOPAD(0x3648, PIN_INPUT | MUX_MODE0) /* uart3_rxd */
DRA7XX_CORE_IOPAD(0x364c, PIN_OUTPUT | MUX_MODE0) /* uart3_txd */
>;
};
};

&uart3 {
status = "okay";
u-boot,dm-pre-reloc;
pinctrl-names = "default";
pinctrl-0 = <&uart3_pins_default>;
interrupts-extended = <&crossbar_mpu GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH
&dra7_pmx_core 0x248>;
};

and mux.h 

{UART3_RXD, (M0 | PIN_INPUT)}, 
{UART3_TXD, (M0 | PIN_OUTPUT)}, 

Can you confirm from your side is this correct? also what else i need to check

Anil Dali 

waiting for your ans.

Thanks

Hi Anil Dali ,Kemal R. Shakir 

Please check

Hi Hanmant,

Can you please include this in early_padconf structure in the mux_data.h file, rebuild and test.

Note: 

I see in the schematics of AM572x_IDK : 

UART3_Txd : Y1

UART3_Rxd: V2 

Which is correct. But as I don't have the exact schematics you shared, Not able to see SN74LVC device.

Can you please share me the schematics that you are using.

Regards,

Anil

Hi Anil Dali ,

same early_padconf  im using but there is no debug logs.

UART3_Txd : Y1

UART3_Rxd: V2  correct im using these balls.

apart from this do i need to change anywhere ?

Hanmant Gaikwad said:

dcan1_pins_sleep: dcan1_pins_sleep {

  pinctrl-single,pins = <

   DRA7XX_CORE_IOPAD(0x364C, MUX_MODE15 | PULL_UP) /* dcan1_tx.off */

   DRA7XX_CORE_IOPAD(0x3648, MUX_MODE15 | PULL_UP) /* dcan1_rx.off */

  >;

and we should not use MODE15 for 

UART_Txd and UART_Rxd pins.

If there is no change in the "am57xx-idk-common.dtsi" and "Mux.h" the older version and newer version, It should work.

Anil

and also we need to remove the following lines from core_padconf_array_essential_am572x_idk[] structure in Mux.h file

Hanmant Gaikwad said:

{UART3_RXD, (M11 | PIN_INPUT_PULLDOWN)}, /* uart3_rxd.pr1_mii0_rxdv */

 {UART3_TXD, (M11 | PIN_INPUT_PULLDOWN)}, /* uart3_txd.rp1_mii_mr0_clk */

Regards,

Anil

checked after removing these lines as still there is no output.

can you please share me the 2016 .dtsi file.

Check this 2016 dtsi file

can you share me "am57xx-industrial-grade.dtsi" file as well.

can you please change interrupts-extended parameters as below:

&uart3 {
status = "okay";
interrupts-extended = <&crossbar_mpu GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH
&dra7_pmx_core 0x248>;
};

but here i see that uart2_ctsn and uart2_rtsn are being selected instead of UART3_RXD and UART3_TXD?

muxMode as 0?

If you have the schematics can you please share here?

Regards,

Hi Anil Dali 

Check out the Debug uart schematic 

Keerthy J  do you have any idea about this?

Hi Anil Dali ,Keerthy J 

Problem got resolved after changing the EMIF registers .

Now the issue is diffferent check logs attached

Hello Hanmant,

I am out of office until tomorrow. 

Best,

Josue

Hi Josue,

Thanks for reply.

No issue.

Please reply once you back

Thanks 

Hanmant

Hello Hanmant,

I will be looking at your your issue today. This Prefetch abort is usually an issue with the CPU trying to execute code from an invalid memory location. In this case you are trying to execute from pc : [<00000118>] which is not valid.

Could you share working logs? 

Are you essentially migrating from an older SDK to a newer SDK?

Any HW changes?

-Josue

Hi Josue Zamitiz-Ayala ,

I had using 2016 uboot version and it's working fine but now I wanted d to use 2019 U-boot version.

I had did same changes in ddr configuration as I did in 2016 U-boot version.

Hello Hanmant,

It is hard to tell what exactly could be the reason you are seeing this abort. Given the thread history, and the diff you shared I have some ideas that can perhaps help guide you.

1. What piece of code is telling the CPU to branch to such a low address? that is one place to start.
   

   prefetch abort
   pc : [<00000118>]          lr : [<841002f0>]

2. Please look into this app note: https://www.ti.com/lit/an/sprac44a/sprac44a.pdf
   
   To ensure the IO timing values published in the Timing Requirements and Switching Characteristics tables of the AM57xx data manual over the lifetime of the device, the AM57xx software must implement the proper pad configuration requirements. The impact of not following these requirements may not be observed immediately. However, in the long term, failure to adhere to this procedure may cause system issues.
   
   
   1. Changing padconfig via DT should be avoided when possible.
3. The issue you are seeing could still be a DDR issue
   1. Did you follow the DDR app note: https://www.ti.com/lit/an/sprac36e/sprac36e.pdf?
   2. Why did you have to change these?
   3. Can you enable more logging in order to figure out your issue?
      EX: 

      # CONFIG_SYS_CONSOLE_INFO_QUIET is not set
      
      CONFIG_DEBUG_UART=y
      CONFIG_DEBUG_UART_OMAP=y
      
      CONFIG_LOGLEVEL=7
      CONFIG_LOG=y

Hi Josue Zamitiz-Ayala 

Can you please check this thread, AM5728: What was the resolution to the previous poster's issue? 

These changes we did in ddr3 in hardware level.

After that same we were facing but after changing ddr registers that's emif,dmm,lisa etc it works fine with 2016 u- boot version.

Thank you for the background Hanmant,

How did you solve the prefetch abort on that version of U-boot?

Hi

It was not resolved that time.

But we wanted to resolve this problem now.

Suggest us any changes do I need to do in dts or defconfig file or elsewhere.

Or any debugging suggestions 

Is there any application loading address changes?

I am confused, you sent me a working boot log of Uboot 2016 https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1650171/am5728-am5728-u-boot-2019-version-issue-with-uart3/6368831, but you are saying -

Hanmant Gaikwad said:

But we wanted to resolve this problem now.

Is the working log with the older DDR layout and the issue with the new layout from this post  AM5728: What was the resolution to the previous poster's issue? 

The evidence still points at an issue with your DDR.

I am not sure that I understand the loading at loadaddr=0x84100000 and then kernel_addr_r=0x82000000
loadaddr=0x82000000 ...

Is this a VxWorks deal? For this you have to contact WindRiver.

Hi Josue Zamitiz-Ayala 

Any update on this.

The onus is on your side.

Josue,

We don't see any logs on console  After making this parameters.

Hanmant,

Could you investigate what code at lr : [<841002f0>] is making the system branch so low (<00000118>])
## Starting application at 0x84100000 ...
prefetch abort
pc : [<00000118>] lr : [<841002f0>]
reloc pc : [<81899118>] lr : [<059992f0>]

Also, try only using 

CONFIG_LOGLEVEL=7
CONFIG_LOG=y

debug uart might not be having the effect we desire. 

Can you clarify how you have a working log from 2016 u-boot and you are saying the prefetch abort was not resolved in the other thread? 

What are the differences? 

-Josue

Hi Josue,

After these no effect at all

CONFIG_LOGLEVEL=7
CONFIG_LOG=y

still this issue is pending https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1304710/am5728-am5728-sd-u-boot-issue but this is related to u-boot 2021 version . 

Josue do you have any other solution to check/ debug.

also check e2e.ti.com/.../am5728-what-was-the-resolution-to-the-previous-poster-s-issue

This is essentially the same issue in all three versions of U-boot., only when you run the Vx-Works application. We do not debug Vx-works, you will have to reach out to Wind River for this. My last question is still pending.

-Josue

After changing the DDR register configurations in u-boot 2016 with same VxWorks bin but same DDR changes it did in fact im doing this 2019 u-boot version as well but there issue of prefetch abort.

I dont understand why this happening

Hello,
Thank you for your inquiry. **Josue Zamitiz** is currently on leave and will be available on **2026-06-12**.
Your query will be addressed upon their return. We appreciate your patience and understanding.
