U-boot flashing in code-warrior USB TAP

[abineshselvaraj]

Hi,

We are using P1020E-WLAN board for our software porting. Now, the U-boot got corrupted and the board fails to boot. To recover it, we are using code-warrior USB tap and installed the code-warrior IDE version 10.2.1 to flash u-boot in NOR flash. When we try to connect and download the u-boot.bin file, it shows the below error,

"Flash algorithm fails to download in DDR, check DDR configuration is correct and flash base-address is proper" .

Is it means that, the target initialisation files for P1020WLAN are not supported in IDE. If yes, is it possible to share initialisation files for P1020WLAN board.

Thanks & Regards,

S.Abinesh.

Hi,

Please find the attached error message shown in code-warrior IDE when we try to download the u-boot bin file.

Hello abinesh selvaraj,

P1020RDB DDR controller configuration parameters are not suitable for P1020WLAN.

Please try to use the attached SRAM CodeWarrior initialization file to use L2 Cache as SRAM to avoid to use DDR.

Have a great day,
Yiping

Hello Yiping,

Thanks for the valuable information. I'm getting the same error, even-after using the attached P1020RDB_init_sram.tcl file as target initialisation script (shown in attached snapshot "CW_snap1").

I have created a flash programmer task by using custom xml file (P1020WLAN_NOR_FLASH.xml) updated with P1020WLAN NOR flash base address (0xee000000) and size  (shown in attached snapshot "CW_snap2"). Kindly verify the flash programmer actions,target ram address and offset in this snapshot.

Also, I found few other initialization files as shown in snapshot "CW_snap2". Do we need to update these files for WLAN board?

Regards,
