TDA4VM: Change the OSPI1 Flash layout

hutian

Part Number: TDA4VM

Hi experts,

I am using SDK 7.1 and setting the boot mode for OSPI1. i have a default flash layout as the User Guide Said:

      0x0 +----------------------------+
          |     ospi.tiboot3(512K)     |
          |                            |
  0x80000 +----------------------------+
          |     ospi.tispl(2M)         |
          |                            |

New SDK V7.1 bind the MCU1_0's OS in tiboot3.bin , when i get a tiboot3.bin larger then 512K, how to change the layout of the flash?

Thanks,

Hi Hutian,

There is an open issue with the OSPI boot in SDK7.1. Please see https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/07_01_00_10/exports/docs/devices/J7/linux/Release_Specific_Release_Notes.html#known-issues-limitations

Is there a possibility to use SDK7.0 if you need to use OSPI?

Regards,

Karan

Hi Karan,

Our custom board has designed to use OSPI Flash to BOOT, and wants to booting the mcu1_0 and mcu2_0 from the MCU domain's SPL. The SDK7.0 doesn't support loading rproc fw from SPI FLash and you will get the following log from serial port:

U-Boot SPL 2020.01 (Jan 04 2021 - 19:18:18 +0800)

Trying to boot from SPI

I want to know whether exists a workaround for the OSPI issue?

Thanks,

hutian

Hi Hutian,

Loading firmwares from OSPI is not supported from R5 SPL, but I believe you can try to load them from u-boot. Can you please take a look at https://e2e.ti.com/support/processors/f/791/p/941650/3489991#3489991 ?

Also, this is a separate discussion from the original question posted, can you please create another e2e for it.

Regards,

Karan

Hi Karan,

Thank for your advice, but there is another question:

i need to disable the SPL in A72 to loading mcu1_0's OS firstly then i can load them at u-boot stage.

i try to disable it by the following strategy, but failed:

at "ti-processor-sdk-linux-j7-evm-07_01_00_10/Makefile"

#UBOOT_DM=$(TI_SDK_PATH)/board-support/prebuilt-images/ipc_echo_testb_mcu1_0_release_strip.xer5f

321 u-boot-a72:
322 @echo ===================================
323 @echo Building U-boot for A72
324 @echo ===================================
325 $(MAKE) -j $(MAKE_JOBS) -C $(TI_SDK_PATH)/board-support/u-boot-* CROSS_COMPILE=$(CROSS_COMPILE) \
326 $(UBOOT_MACHINE) O=$(UBOOT_A72_BUILD_DIR)
327 $(MAKE) -j $(MAKE_JOBS) -C $(TI_SDK_PATH)/board-support/u-boot-* CROSS_COMPILE=$(CROSS_COMPILE) \
328 CONFIG_MKIMAGE_DTC_PATH=$(UBOOT_A72_BUILD_DIR)/scripts/dtc/dtc \
329 ATF=$(UBOOT_ATF) TEE=$(UBOOT_TEE) DM=$(UBOOT_DM) \
330 O=$(UBOOT_A72_BUILD_DIR)

and get the failed log:

Could you help me to disable it ?

Hutian,

You could just rename firmware name, so that SPL does not load it.

Hi Brijesh,

Rename the mcu os will be still failed.

ti_sci_get_response: Message receive failed. ret = -110
Mbox send fail -110

resetting ...
ti_sci_get_response: Message receive failed. ret = -110

Could you check it under SDK 7.1 at your side?

Thanks,

Hi Hutian,

This seems some different error, If you remove all firmwares from /lib/firmware folder, does this error come from uboot? Wondering if this is coming due to firmware loading.

HI Brijesh,

i can stop at the u-boot comand line , but if i try to load mcu1_0's OS, i get the following error:

=> rproc init
Remote Processors are already initialized
=> load mmc 1 0x90000000 j7-mcu-r5f0_0-fw

Hi Hutian,

Can you change name of the file j7-mcu-r5f0_0-fw in /lib/firmware and then try loading from uboot?
