Partitioning of qspi-nor

[rja]

Hi, we would like to put our custom image and u-boot on qspi-nor. We are having trouble with the partitioning in the qspi it seems to automatically create a 1MB partition and we would like to make this custom. How might we go about this? Where does this occur in the mfgtool action? I don't see anything about it in the ucl2.xml file.

Hi Ryan

one can look at attached vbs script from mfg tool for L4.1.15_2.0.0-ga_MX6SCM

and try to use them with mfg tools from software link

i.MX Software | NXP

Hi Igor,

Thank you for your response, I see the flash_erase and dd commands in your ucl2.xml file for /dev/mtd0 through /dev/mtd3. However, on our evk we are not seeing anything besides /dev/mtd0. I would like to know where in the mfgtool the qpsi is actually being partitioned. Where are /dev/mtd1 , /dev/mtd2 and /dev/mtd3 being created?

Thanks

Ryan

Hi Ryan

one can look at sect.4.6 Flash memory maps attached Linux Guide, Chapter 31
SPI NOR Flash Memory Linux Manual, scm linux sources

linux-imx - i.MX Linux kernel
