FMC tool relaunch error

[dmitryslezkin]

Hello!

I'm trying to dynamically reconfigure PCD by using fmc tool where it's first launch looks like successfull (and my developed application works fine) but if I'm trying to re-use fmc, it returns the following errors:

ERR : Invocation of FMcpu8/8: ! MAJOR FM-PCD Error [CPU08, drivers/net/ethernet/freescale/fman/Peripherals/FM/Pcd/fm_kg.c:3003 FM_PCD_KgSchemeSet]: Resource Already Exists; _PCD_Disable for

cpu8/8: Scheme id (0)! fm0/pcd failed cpu8/8:

ERR : Invocation of FM_PCD_Disable for fm0/pcd failed with error code 0x00010028

My target: T4240RDB,

SDK version: 1.8,

command sequence used:

cd /usr/etc

fmc -c usdpaa_config_t4_48g.xml -p usdpaa_policy_hash_ipv4.xml -a # it's ok

fmc -c usdpaa_config_t4_48g.xml -p usdpaa_policy_hash_ipv4.xml -a # same for example; fails with above errors

Is it wrong or the problem can be caused by some dts(dtb) errors, or something else?

Thank you!

Hello Dmitry Slezkin,

The FMC Tool directly configures the FMan, it passes the configuration it finds in its input files (along with compiled Soft Parser firmware) to the FMan driver which, in turn, modifies the FMan's configuration.

The FMC Tool does not support dynamic FMan configuration; you can use the tool to configure the FMan just once, typically at application initialization.

Have a great day,
Yiping
