TMDS64EVM: OSPI Boot Failure on TMDS64EVM EVK

Jack

Part Number: TMDS64EVM

Hi TI

A customer has purchased TMDS64EVM and is trying to get OSPI booting based on the latest SDK 9.2.x.

When the boot mode is SD Card, it boots normally, but when the boot mode is changed to OSPI, it does not boot, so we are contacting you.

In the case of Bootmode OSPI Flash, the procedure was as follows.

1. Flash u-boot (tiboot3.bin/tispl.bin/u-boot.img) from “mmc 1:1” to OSPI

=> mmc rescan

=> sf probe

=> load mmc 1:1 ${loadaddr} tiboot3.bin

=> sf update $loadaddr 0x0 $filesize

=> load mmc 1:1 ${loadaddr} tispl.bin

=> sf update $loadaddr 0x80000 $filesize

=> load mmc 1:1 ${loadaddr} u-boot.img

=> sf update $loadaddr 0x280000 $filesize

2. Power off and change Bootmode to OSPI Flash with EVM Boot Device selection

- SW2.4 on / SW2.8 off / SW3.1 on

===================================

There is no log on Console after power on.
If you change the Bootmode to SD Card, it boots normally.
Please let me know if it didn't work, or if there is a procedure to add.

I refer to the following guide regarding Bootmode SW setting, but I don't know how to set the lclk Csel value of SW2.8 and SW3.1. Please let me know.

Thanks.

Hi Jack,

Could you please use the bootmode pins settings as shown here

Hi Jack,

In addition to the previous suggestion, I notice you are using wrong offsets to flash the images. The correct sequence is:

=> load mmc 1:1 $loadaddr tiboot3.bin
612130 bytes read in 58 ms (10.1 MiB/s)
=> sf update $loadaddr 0x0 $filesize
device 0 offset 0x0, size 0x95722

87842 bytes written, 524288 bytes skipped in 1.530s, speed 408618 B/s
=> load mmc 1:1 $loadaddr tispl.bin
1017203 bytes read in 73 ms (13.3 MiB/s)
=> sf update $loadaddr 0x100000 $filesize
device 0 offset 0x100000, size 0xf8573

=> load mmc 1:1 $loadaddr u-boot.img
1335119 bytes read in 86 ms (14.8 MiB/s)
=> sf update $loadaddr 0x300000 $filesize
device 0 offset 0x300000, size 0x145f4f

Hi Prashant

Based on the data you sent, I changed the OSPI Bootmode on the EVM board and confirmed that it booted normally.
And I have already changed the offset of Flash Image and applied it.

Thanks.

Jack
