Unable to get console for booting from sdcard

shrikantchikodi — Fri, 20 May 2016 05:35:59 GMT

Hello ,

I am using Vf5xxR series board. I want to boot it from sdcard. I have done following jumper setting on the board.

In order to boot from the SD interface, the following switches must be turned ON. The

RCON bits switches must be set ON is in the up position.

o [SW10] -5, 6

o [SW11] - 11

o Jumper J15 is on pins 2 and 3

At the offset of 1k i have flashed my uboot.

I have connected the board to Linux-PC with a 9-pin RS232 cable and started mini-com.(/dev/ttyUSB0)

But I am not able to get the u-boot console.Do I am missing some jumper settings.Or i am missing some steps for sdcard boot.

Thanks,

Shrikant

Hello Shrikant,

which board you use?

27419 uses SCI0

and

28141 uses SCI2

to create UART interface.

Please check you U-Boot code which SCI is used there.

Hi Jiri,

I am using VF522R3 SCH-28141 REVB2 board. I want to boot the board. I have taken the Uboot source code from MFG tool directory and change the UART1 to UART0 as mentioned in this patch u-boot source code for EVB-VF522R3 .

I built the uboot source code using arm-noneabi- tool chain. I try to download the uboot using following command.

$ dd if=u-boot.imx of=/dev/sdb1 bs=1k seek=1

$ sync

I inserted the card in to the VF522R3 SCH-28141 REVB2 to boot. It does not give any output on serial console. Please help.

Also i have downloaded the .img file and i want to flush it on SD Card to check the board boot status. Please guide which command i can use to flush Vybrid-EVB-Demo-Validation.sd.img to card.

Thanks,

Hemal

Hello Hemal,

28141 which you are have uses SCI2 (UART2).

The patch is from TWR-VF65 (SCI1) to 27419 (SCI0)
