Hello, With excuses I found in a post to your order:
"boot console=ttyS0 root=/dev/mtdblock4 rw rootfstype=jffs2 init=/bin/sh" replacing the existing one: "boot console=ttyS0 root=/dev/mtdblock4 rw rootfstype=jffs2 init=/linuxrc" used it and now does not pass this pass:
amboot> reboot
▒
the spinor flash ID is 0xC21820C2
### PTB check by sy 20161119
### gpio init ###
flspinor addr = 0x00200000, size = 0x00DF0000
flspinor addr = 0x00050000, size = 0x001B0000
flspinor addr = 0x00040000, size = 0x00010000
flspinor addr = 0x00010000, size = 0x00030000
flspinor addr = 0x00000000, size = 0x00010000
What happened? Good or bad?

It's not getting as far as booting the kernel.
Which did happen OK when you used the 'boot' command by itself previously.
This would be the normal startup when the kernel is booted.

With the rigorous excuses I come back with my problem. Today I looked closely at my router, more precisely at the port on which the webcam is located, and I noticed that when I energize the power supply and remain locked during the boot, the LED is on, but when I go through the ESCAPE procedure on AMBOOT, the LED is off. This makes me think that the ETH port on the physical webcam is good, but with internal commands it fails to get up. Do you have any suggestions yet?

If it would be possible to get to the Linux shell by the use of the
init=/bin/sh
boot param, then the command
ifconfig eth0 192.168.1.64 up
would normally configure the Ethernet port.

That's the bootloader.
You'd need to boot it with the boot command and the normal parameters and include the init=/bin/sh instead of the linuxrc

OK, no shell prompt there.
The kernel starts, but the root file system does not exist.
It was worth another try.

Good evening, with excuses come back to my problem. Post # 59 refers to folding the tftp server, but I do not come to it because I have "Link down". I want to use an SD card with these files on it, but I do not know what format the card should have ex. ntfs, fat32, or other format, and what capacity should they have. I also do not know what commands I give it to rewrite these files into the flash IP camera memory. Please make an effort to help me with this problem.

I'd guess that FAT32 will be most likely to be supported.
Copy the files to the SD card, and at the root shell command, see if the card has been automatically recognised and mounted with the 'mount' command.
Check if the device exists by looking at the result of the command
ls -l /dev
and look for a device that may begin with something like mmc

What capacity should the SD card, 16 Gb, 32 Gb? IP camera accepts them or must be smaller 4Gb, 1Gb?
