TDA4VM-Q1: How to make SBL for SPI boot mode

I want to boot from SD card, program NOR in uboot

Hi,

I am sorry, I am not getting the question here. There is OSPI SBL available in RTOS SDK at <PDK_Install_Path>\packages\ti\boot\sbl\binary\j721e_evm\ospi\bin. Is this default image not working for you. If not, what errors are you facing with that?

Hello Parth,

The size of my NOR flash is 16M,

I see that the command you programmed is

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

=> sf update ${loadaddr} 0x280000 0x${filesize}

=> fatload mmc 1 ${loadaddr} sysfw.itb

=> sf update ${loadaddr} 0x6C0000 0x${filesize}

All of them are < 16 MB. The highest address is 0x6C0000 which is around 6 MB.

You should be able to boot even without the nor_spi_patterns.bin.

Can you try without nor_spi_patterns.bin on your flash?

Hello Keerthy,

SPL is a success,

I set cmd =  SNOR_CMD_PP in linux, How to modify the same way in SBL.

At the same time I added a Macronix

This Macronix is what I added in linux,

Where is the same modification in RTOS

Hello Keerthy,

I had this problem while initializing

log:"Invalid magic number in Single image header"

When I make an app, the bin file used is in the directory <PDK_Install_Path>\packages\ti\boot\sbl\binary\j721e_evm\ospi\bin

You don't need to use 0x3fe0000. nor_spi_pattren.bin needs to be flashed at the last sector of your flash. 

Modify OSPI_INDAC_TRIG_ADDR in <PDK>/drv/spi/src/v0/OSPI_v0.c to the address of the last sector of your flash. Rebuild the SPI driver, rebuild the SBL and then flash the nor_spi_pattern.bin at the last sector of your flsh.
