TDA4VM: How to transplant cypress's s28hs512t (OSPI) based on the SDK version 7.2 of the j721e platform

Hi Jordon,

I recommend going through this FAQ:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/946418/faq-tda4vm-is-there-a-guide-to-choosing-the-right-ospi-flash-parts-that-are-supported-on-jacinto-7

So that is supported. What do you mean by transplant? Are you trying to use a different flash part?

Hi Keerthy,

I am using the J721E platform, and the OSPI model supported by default is MT35XU512. But what should I do if OSPI is changed to S28HS512T? My SDK is based on J721E version 7.2.

The official information tells me that the J7200 platform supports S28HS512T by default. I now port part of the driver to the J721E SDK. Now I can erase and write S28HS512T, and I did a read and write test to verify that the written file and the data I read out are Consistent. But after I set it to OSPI startup, no information was printed. How can I do it? Thank you!

Hi Keerthy,

Based on J721E Linux 7.2 SDK, I modified the partition information to adapt to S28HS512T, the information is as follows:

Hi Jordan,

Can you follow: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/08_00_00_08/exports/docs/linux/Foundational_Components/U-Boot/UG-QSPI.html

Section: 

3.1.1.7.1. AM654/J721E Support

Download the phy calibration pattern from the above link as mentioned in the snapshot below:

Then you need to flash the phy calibration pattern:

Note that phy calibration pattern is at 0x3fc0000 for the S28HS512T part.

Could you try and let me know if the OSPI boot works for you?

Hi Keerthy,

You can see that I have set the starting address of the pattern partition(ospi.phypattern) to 0x3fc0000, and I did it according to the user manual. My problem is that I have burned the file to the partition, but there is no print information after I set it to OSPI boot mode.

We need your help to confirm whether the room code of the chip we got (XJ721EGBALF) supports S28HS512T? We also tried the SPI boot method, but did not start successfully.

BR,

Jordon

Hi Jordon,

I checked with OSPI expert. The S28HS512T flash part is only supported on silicon revision ES1.1 Silicon for J721e. Can you confirm the
Silicon revision of your part.

You can easily check that from your U-Boot logs like below:

U-Boot 2021.01-00002-gf2b2a890f8 (Sep 16 2021 - 17:56:09 +0530)

SoC: J721E SR1.0
Model: Texas Instruments K3 J721E SoC
Board: J721EX-PM2-SOM rev E6
DRAM: 4 GiB
Flash: 0 Bytes

 Also S28HS512T  part works with 8.0 SDK on ES1.1 silicon in xSPI boot mode:

DIP Switch settings:

SW8: 10000010
SW9: 00110000
SW3: 0111001010

I confirm that J721e SR1.0 will not work with S28HS512T  both in SPI and xSPI mode.

Hi Keerthy,

After I boot from the TF card, u-boot prints the following information:

-----------------------------------------------------

SoC: J721E SR2.0
Model: Texas Instruments K3 J721E SoC
Reading on-board EEPROM at 0x50 failed 1
Board: J721EX-PM1-SOM rev E2

Reading on-board EEPROM at 0x50 failed 1
Net: Could not get PHY for ethernet@46000000: addr 0
phy_connect() failed
No ethernet found.

---------------------------------------------------------

The actual situation is that J721e SR2.0 cannot work with S28HS512T  both in OSPI and xSPI mode, no information is printed. 

But J721e SR2.0 can work with S28HS512T in SPI mode: 

After about ten seconds, the print information is as follows:

Still did not start successfully.

Do you have a patch about J721e SR2.0 work with S28HS512T based on SDK 7.2?  I also tried to replace tiboot3.bin of sdk 8.0, but it still did not start successfully.

BR,

Jordon

Hi Jordon,

I recommend taking all the boot binaries from SDK 8.0 i.e tiboot3.bin, sysfw.itb, tispl.bin, u-boot.img.

Can you try that with xSPI boot mode-

DIP Switch settings:

SW8: 10000010
SW9: 00110000
SW3: 0111001010

Let me know if that works.

Best Regards,
Keerthy

Hi Keerthy,

I have taked all the boot binaries from SDK 8.0 i.e tiboot3.bin, sysfw.itb, tispl, u-boot.img.

I tried the boot method of xspi and spi, the log prints the same information, as follows:

Have you verified the J721E+S28 solution successfully with the 8.0 SDK?  Can you show me the printed information after your successful boot? 

BR,

Jordon

Hi Jordon,

The default TI EVM comes with the Micron flash. I will try to check with other HW & get back to you. It will take some time.
