Dear Sir,
We are using P1021rdb-pc board with p1021 processor.
1. compilation and build process is taking so much of time. How
should I
reduce the time for linux build process?
Remove things from the .config that you don't need.
Be sure you're using a -j value that is large enough to keep all your
CPUs busy.
Use ccache.
Get a faster build machine. :-)
2. In kernel configuration we are not able to select P1021rdb.,
When we configured the board for p1021RDB-PC , in default kenel
config file all the below platforms are selected , We want only
p1021rdb , what should we select here?
CONFIG_PPC_CELL is not set
CONFIG_FSL_SOC_BOOKE=y
CONFIG_FSL_85XX_CACHE_SRAM=y
CONFIG_MPC8540_ADS=y
CONFIG_MPC8560_ADS=y
CONFIG_MPC85xx_CDS=y
CONFIG_MPC85xx_MDS=y
CONFIG_MPC8536_DS=y
CONFIG_MPC85xx_DS=y
CONFIG_MPC85xx_RDB=y
fsl,P1021RDB-PC is handled by mpc85xx_rdb.c (and thus
CONFIG_MPC85xx_RDB).
3. We are using p1021 processor which has 36 bit support , but we
have compiled uboot for 32 bit only.Is there any specfic use of 36
bit compilation, ?
If your U-Boot is configured for 32 bits, there's no benefit to
enabling CONFIG_PHYS_64BIT (unless you're remapping things yourself,
such as moving the PCIe windows), and it can slow things down.
4. Now we are using SDK 1.3.2 for p1021 procesor .Is there any
specific
necessity that we should switch to sdk1.4
regarding linux drivers specially included for p1021 procesor?
It's generally good to use more recent code for the various
improvements and fixes it contains, but I don't know of a specific
p1021-related requirement. Note that this list is for upstream Linux;
for help with Freescale SDKs go to https://community.freescale.com/
Also note that p1021rdb-pc is supported in upstream Linux; you do not
need to use the SDK at all unless there is something specific you need
beyond basic board support.
5.UMCC driver is available in linux driver ?
No.
where should I get some help regarding UMCC ?
community.freescale.com, supp...@freescale.com, or your sales/FAE
contact.
