T2080 Custom Board: Loading U-Boot into SPI NOR Flash

[Priyaa]

Hi,

We have loaded the u-boot-with-spl-pbl.bin generated by modifying the RCW words with our custom RCW words in QorIQ SDKv2.0, getting error as "Failed to reset the Target(T2080 core not responding)" and no uart console messages

what is the offset address to load the file in SPI NOR flash??

is it the right way to directly load the u-boot-with-spl-pbl.bin file of T2080RDB with just RCW changes??  if no, what are the major modifications to be done in the u-boot source to boot the device from the SPI NOR flash...please guide

Regards,

Priya

You could kindly follow the steps of QorIQ SDK v2.0-1703 Documentation

If you changed the t2080_spi_rcw.cfg with your own RCW but the T2080 customer board still could not boot up, please kindly follow the file below to debug your u-boot.

Have you changed the t2080_spi_rcw.cfg into your own RCW in the u-boot source path/board/freescale/t208xrdb

And then generate the u-boot-with-spl-pbl.bin?

Thanks

Hi June,

The RCW loaded is valid set of RCW words, we confirmed this by just loading the custom RCW bin file and the data is been fetched into the CCSR registers and no error while executing ccs commands

The "u-boot-with-spl-pbl.bin" file is generated by the following commands -

(at the u-boot source path location)

1. make T2080RDB_SPIFLASH_config

2. make

loaded the u-boot-with-spl-pbl.bin at the offset 0x0 of the SPI NOR flash using the flash programmer in the CW IDE..

If get error "Failed to reset the Target(T2080 core not responding)", please confirm the RCW is correct.

If the error is not caused by the RCW, please kindly share how you generate the "u-boot-with-spl-pbl.bin", thanks.
