HI,
How to flash the u-boot into SPI of K2E ?? using PROCESSOR-SDK-LINUX-K2E
Regards
Shankari G
Pre-requisite
Steps:
1. copy u-boot from the built image folder to the tftp boot folder.

2. host/server network configuration - Set the ip address manually.

==================================================
No Ip address is set above, so pls set manually like below.
==================================================
sudo ifconfig enp0s31f6 10.100.1.10 up
ifconfig
3. On device - terminal, please set the environment variables such as serverip and EVM's ipaddress like below.
==========================================================================================
K2E EVM # setenv ethact K2F_EMAC0 --- down port
K2E EVM # setenv ethact K2E_EMAC1 --- top port
K2E EVM # setenv eth1addr 01:02:03:04:05:06
K2E EVM # setenv eth2addr 01:02:03:04:05:07
K2E EVM # setenv ipaddr 10.100.1.11
K2E EVM # setenv serverip 10.100.1.10
K2E EVM # saveenv
K2E EVM # ping 10.100.1.10
Using K2E_EMAC1 device
host 10.100.1.10 is alive
4. Issue tftpboot command
======================
K2E EVM # tftpboot 0x88000000 u-boot-spi_shank.gph
Using K2E_EMAC1 device
---
Please get the size of the u-boot and change the offset accordingly.
For example, the size of the u-boot image size is 0xa1216 and for spi flashing, the size used approximately is 0x100000 ( adding some buffer memory and rounded off the value. These adding buffer and rounding off is not necessary for SPI-flash. You can use the size, 0Xa1216, directly.
May be for NAND with ECC, it might be meaning ful.
---
5 Flashing uboot into SPI:
===================
K2E EVM # sf probe
SF: Detected N25Q128A with page size 64 KiB, total 16 MiB
(Offset depends on u-boot image size )
K2E EVM # sf erase 0 0x100000
K2E EVM # sf write 0x88000000 0 0x100000
===================
Please have a look at the snapshot for each flashing steps.
-----------------------------------
DIP SWITCH setting
SW1 : 0 0 1 0
Press powerON reset button
The newly built u-boot will get booted from the SPI flash
Please verify the Date and timestamp of the u-boot built with the output messages from the device-terminal.
For example, I built the u-boot on 14 May 2022 , and here it shows the same date, 14 May 2022
