you can use y-model on serial to upload firmware.
you should enter u-boot and run loady.
putty sames to cannot send file via y-model, you can install a serial terminal which can send files,
and then send file via y-model

the other way to program firmware is sd/mmc if it is available, you can copy the firmware to sd card
via card reader, and then insert to the board, and then upgrade under u-boot

Hello,

First of all thank you for helping me. I have several questions,

• what is y-model?

• Do you have any links to know how to upload files with y-model or sd / mmc?

from hi35xx-buildroot.

sorry, it's Y-modem, it is a file transfer protocol over serial port.
it can be use to transfer files from host pc to target board via serial port.
u-boot has y-modem support, loady command can be used to receive file.
on the other hand, you must have a serial terminal supports y-modem,
as i know, SecureCRT supports x/y/z-modem protocol, if you have a linux host,
minicom also has y-modem support.

to transfer file from the host pc to board, first run loady command on the target board

loady 0x81000000

and then you can send file, if you are using SecureCRT, open the "transfer" menu, select
y-modem protocol, and then select the file to transfer.
i'm using linux, only have minicom installed, press CTRL+A,S , and select ymodem protocol,
then select which file to transfer.
after transfer completed, the file will be saved to address 0x81000000.

Ok xuhuashan, I tested with ExtraPutty and I send the file with Y-Modem, but now???

My firmware is "General_HZXM_IPC_HI3518E_50H10L_8188_S38_V4.02.R12.Nat.20161214_ALL.bin" from http://www.hasecu.com/DOCs/Firmware/General_HZXM_IPC_HI3518E_50H10L_8188_S38_V4.02.R12.Nat.20161214_ALL.bin
