Complete Boot from QSPI nor flash for imx6ull and MFG(4.9.11) tool support to flash u-boot, kernel,dtb and rootfs

[jayebc]

Hi all,
>>     I am using imx6ull nxp board. In the reference board 32MB(256Mb) QSPI nor flash is used. Is it possible boot from QSPI by flashing complete u-boot,kernel, dtb and   
        rootfs to QSPI nor flash?
>>  I have tried flashing using mfg tool(4.9.11), but I am able to flash only U-boot(see below logs).

 >> OR We need to use QSPI nor flash only for u-boot? The kernel, dtb rootfs should be loaded to other boot device?

Eagerly waiting for response. Please help if someone already worked on it.

Thanks in advance

Hi Jaya

>> Is mfg tool(4.9.11) supports to flash complete OS(u-boot,kernel, dtb and rootfs) to QSPI nor flash?

it may not support as full size of these images may be too big to fit to qspi.
One can try to generate small rootfs so overall size of these images will fit to qspi.

>> OR We need to use QSPI nor flash only for u-boot? The kernel, dtb rootfs should be loaded to other boot device?

one can look at example for SCM it has example for spi programming all images, for qspi it will be similar.

Programmers (Flash, etc.)
SCM_IMX6_M6.0.1_2.1.0_MFGTOOL
SCM-i.MX 6 Series Manufacturing Toolkit for Linux 4.1.15_2.0.0
Quick Start Board for SCM-i.MX 6DQ|NXP

Hello Igor,

Noe I am able to flash U-boot. But I wanted to test qspi by writing and reading it back. With this I need to test all sectors of qspi. Could pleaase suggest me  how I need to test all sectors of QSPI  to shoow all sectors are fine.

Thanks and Regards,

Jaya

Hi Jaya

one can try read/write tests from uboot:

sf erase, sf write, sf read

Hi Igor,

Actually  I want to know the memory address(start and end address) for 256mb qspi and how I can test using above commands so that I can test all sectors of QSPI nor flash.

Thanks in advance

Hi Jaya

for qspi memory address one can look at

Table 2-1. System memory map i.MX6ULL Reference Manual
