Hi Everyone. I hope to modify the RCW setting in LSDK2012,but it is failure, I do following steps according the user guide:

1.modify the setting packages/firmware/rcw/ls1021atwr/SSR_PNS_30/rcw_1200_sdboot.rcw, the CGA_PLL1_RAT old item is 12, I change it as 10

2. use the command flex-builder -c rcw -m ls1021atwr -b sd to generate new rcw_1200_sboot.bin

3.use the command flex-builder -c uboot -m ls1021atwr -b sd to generate new uboot image uboot_ls1021atwr_sdcard_ifc.bin  but the RCW bits in uboot is still as before.(from the manifest file

I can assure such file : uboot_sdboot=$FBOUTDIR/firmware/u-boot/ls1021atwr/uboot_ls1021atwr_sdcard_ifc.bin)

for the new rcw_1200_sdboot.bin the first 24 bit is AA 55 AA 55 01 EE 01 00 06 08 00 0A

the old rcw_1200_sdboot.bin the first 24 bit is        AA 55 AA 55 01 EE 01 00 06 08 00 0C

so the RCW binary file had been modified sucessfully.

but the first 24bit in uboot_ls1021atwr_sdcard_ifc.bin is same as old rcw file

why ?  Is there any wrong operation ?please give suggestion about it. Thank you!

Use the following command sequence:

  1. Change RCW in .cfg file in u-boot source folder. Use the following path:

/flexbuild_lsdk2012/packages/firmware/u-boot/board/freescale/ls1021atwr

  1. use the command "flex-builder -c uboot -m ls1021atwr -b sd" to generate new uboot image uboot_ls1021atwr_sdcard_ifc.bin

This file available using the following path: /flexbuild_lsdk2012/build/firmware/u-boot/ls1021atwr
