2. Download & Building Source

Source File Tree, files structure based on Econet en_7580 sdk.

2.1 Make Building

decompress SDK and building the source

root@:# mkdir -p releasebsp
root@:# cp releasebsp_profilename_relasedate.tgz ./releasebsp
root@:# tar -xzvf releasebsp_profilename_relasedate.tgz
root@:# fakeroot make PROFILE=NP_EN7561D_LE_7592_7613_NORD_64M_demo CUSTOM=CT clean 
root@:# fakeroot make PROFILE=NP_EN7561D_LE_7592_7613_NORD_64M_demo CUSTOM=CT All

root@:# fakeroot make PROFILE=NP_EN7561D_LE_7592_7613_NORD_64M_demo CUSTOM=CT bootbase_clean bootbase
root@:# fakeroot make PROFILE=NP_EN7561D_LE_7592_7613_NORD_64M_demo CUSTOM=CT buildimage

generate image at ''releasebsp/Project/images/tcboot.bin " , "releasebsp/Project/images/tclinux.bin"

to build misc image by following:

root@:# ./addoob tclinux_allinone_nand tclinux_allinone_nand_ecc 2048 64
root@:# ./addhdr tclinux_allinone_nand_ecc ap_mstc.bin

(Note: check hex data for MSTC image , verify the offset data correct or not , ./addoob file1 file2 2112 64 .)

3. BootLoader

Source file tree (based on en7528).

├── strat.S
│	(copy from "start.S_7510_final".)
├── bootram/
│	(main bootbase driver such as network ,flash and bootbase command.)

├── spram_ext/	
├── lzma/
├── unopen_img/
├── verify/
├── bootload.c
├── header.c
├── byteswap.c
├── lzmaload.c
├── mic.c
│	( copy 'mi.cfg' and make to global var on tcboot.bin)
├── make_bootbase
└── Makefile

(Note: the Econet's boot-loader same as u-boot, driver's source files at bootrom/bootram , IPL( Initial Program Loader))

whole bootloader make command:

make -C bootram  TCSUPPORT_SECURE_BOOT_AES=0 TCSUPPORT_BB_CHECK=1 TCSUPPORT_BB_FIX_UNOPEN=1 TCSUPPORT_SPI_CONTROLLER_ECC=1 TCSUPPORT_SPI_NAND_FLASH_ECC_DMA=1 TCSUPPORT_MIPS_1004K=1 L2CACHE_LOCK_CODE=1 TC3262=1 SIS_DDR_PHY=1 RT63365=1 MT75XX_REDUCE_SIZE=1 TCSUPPORT_CPU_EN7528=1 MT75XX_REDUCE_SIZE=1 TCSUPPORT_CPU_EN7512=1 64M=1 TR068_LED=1 TCSUPPORT_FREE_BOOTBASE=1 CONFIG_DUAL_IMAGE=1 TCSUPPORT_BB_256KB=1 MT75XX_NAND=1 EN7512_NAND=1 TCSUPPORT_10G_FPGA_DDR4=1 SPI_NAND_FLASH_DEBUG=1 SPI_CONTROLLER_DEBUG=0 SPI_ECC_DEBUG=0 SPI_NFI_DEBUG=0 BOOT_LZMA_SUPPORT=1

4.1 process to building tclinux.bin

making tclinux.bin based for en7528 , profile based CT_EN7561D_LE_7592_7613_AP_demo

make -j 16 -C /home/chear/MTK/tclinux_phoenix_ctc_20200308/linux-3.18.21 linux.7z
../tools/lzma e linux.bin linux.7z
../tools/trx/trx -f linux.7z -o linux.7z.trx -c ../tools/trx/trx_config
../../tools/trx/trx -k 4149365 -r 15364054 -u 0x80002000 -f tclinux -o tclinux.bin -c ../../tools/trx/trx_config

5. CFG command

# tcapi show Account_TelnetEntry
OID [183:1][TelnetEntry]:
	[Active = Yes]
	[telnet_username = e8telnet]
	[telnet_passwd = e8telnet]
	[telnet_port = 23]

# tcapi set Account_MfgMode Active "Yes"
(Note: update romfiles)
# tcapi save

# prolinecmd restore default

# sys led on

(Note: default backup romfile path: userfs/romfile.cfg , running romfile path: /dev/mtdblock1 )

​

Econet restore default command:

# prolinecmd romfileselect set ctromfile_prd.cfg
# tcapi show System_Entry 
# prolinecmd restore default
