"cant find part named boot
sunxi_flash - sunxi_flash sub-system

Usage:
sunxi_flash read command parmeters :
parmeters 0 : addr to load(hex only)
parmeters 1 : the name of the part to be load
[parmeters 2] : the number of bytes to be load(hex only)
if [parmeters 2] not exist, the number of bytes to be load is the size of the part indecated on partemeter 1
boota: bad boot image magic, maybe not a boot.img?

Where is the problem?

CORRECT!

Now what should be in boot_normal=
What should u-boot boot and from where (filesystem,partition) it should boot
little help maybe:
http://linux-sunxi.org/U-boot
http://linux-sunxi.org/UEnv.txt

The numbers let them be as they are

OK, I think it's better you understand what you need to change right?
look, this is the default:

1. #define CONFIG_EXTRA_ENV_SETTINGS \
   
2.         "bootdelay=3\0" \
   
3.         "bootcmd=run setargs_nand boot_normal\0" \
   
4.         "console=ttyS0,115200\0" \
   
5.         "nand_root=/dev/nandd\0" \
   
6.         "mmc_root=/dev/mmcblk0p7\0" \
   
7.         "init=/init\0" \
   
8.         "loglevel=8\0" \
   
9.         "setargs_nand=setenv bootargs console=${console} root=${nand_root}" \
   
10.         "init=${init} loglevel=${loglevel} partitions=${partitions}\0" \
    
11.         "setargs_mmc=setenv bootargs console=${console} root=${mmc_root}" \
    
12.         "init=${init} loglevel=${loglevel} partitions=${partitions}\0" \
    
13.         "boot_normal=sunxi_flash read 40007800 boot;boota 40007800\0" \
    
14.         "boot_recovery=sunxi_flash read 40007800 recovery;boota 40007800\0" \
    
15.         "boot_fastboot=fastboot\0"
    

Copy code

What do you think it's needed to change?
look at you error messages.
You have not posted the complet error log.
repost:

cant find part named boot
sunxi_flash - sunxi_flash sub-system

Usage:
sunxi_flash read command parmeters :

if [parmeters 2] not exist, the number of bytes to be load is the size of the part indecated on partemeter 1

hint: cant find part named boot

Have you changed something in #define CONFIG_EXTRA_ENV_SETTINGS?
if yes post what you have changed.
if no ... it does not work if unchanged.

ivan_ucherdjiev

Thank you for your replay!
it is unchanged ... what should i change there ?

ivan_ucherdjiev

i think it is set to boot from NAND and not from SDMMC am i right?
do you have skype ?

ivan_ucherdjiev

ah my bad from it is made to boot from flash and cannot find boot there

ivan_ucherdjiev

If I am right here

        "boot_normal=sunxi_flash read 40007800 boot;boota 40007800\0" \
        "boot_recovery=sunxi_flash read 40007800 recovery;boota 40007800\0" \

sunxi_flash sould be changed to mmc but the the numbers, i do not know for what are they and should they be changed

ivan_ucherdjiev

so maybe it should be
"boot_normal=mmc read 40007800 uImage; boota 40007800\0" \
or
"boot_normal=mmc read 40007800 dev/sdc1/uImage; boota 40007800\0" \

Am i right?

ivan_ucherdjiev

hmm or

"boot_normal=fatload mmc 0 40007800 uImage; bootm 40007800\0" \  
am i right?

by the way thank you very much for your support I am new in linux but i want to learn
