From this menu you can do some basic actions such as delete configuration or upgrade firmware. At this point, I first downloaded the firmware update file from the manufacturer's website. You can flash this file from web GUI or tftp. Basically, this file is a micro updater OS (named BLUP), with some embedded files.

TFTP Upgrade process (the most interesting as it allows to boot directly from RAM) :

As you can see, it downloads the file and starts it. The entry point seems to be 0x5fb0034.

If you try to alter the upgrade file, it tells you "incorrect CRC" but it tells you the correct CRC.

Here is the beginning of the upgrade file :

You can find :

- Magic string at the beginning "TELDAT ClosedEyeVisual"
- The BLUP Image length in Bytes 00027000 (159744Bytes). The CRC is calculated in this area.
- Fisrt Image CRC EC B8 D4 64 at offset 2C
- Second image CRC (which is the same) at offset 30
- Beginning of the BLUP upgrader at offset 34.
- Magic string "CEV" of BLUP at offset 3C

While downloading the firmware, the device checks if the CRC is correct. Then, it verifies if the image is valid (by checking the presence of "CEV" magic). Finally, it writes the entire image to RAM at 0x05fb0000 address. At this point, you can see the first execution begins at 0x05fb0034. If you go to offset 34, you can see the ASM instruction 1000000A which is a jump to offset 0x3E (0A+34). This avoid executing the magic string (CEV) and crash.

For testing purpose, you can run the following commands :

$ dd if=update.cev of=image bs=1 skip=52 count=159744
159744+0 enregistrements lus
159744+0 enregistrements écrits
159744 bytes (160 kB, 156 KiB) copied, 0,190313 s, 839 kB/s

$ crc32 image
ecb8d464

You can see the CRC is correct smile

To execute my own code, I have to put it somewhere after the magic string, and modify the Jump instruction. For simplicity, I choose to put the new code at offset 0x40.

First, I cut the upgrade file to keep only the first 64bytes. This is done with dd.

dd if=upgrade.cev of=header.cev bs=64 count=1

Then, with an hex editor, modify the jump at offset 34 to jump to offset 40 :

10 00 00 02  00 00 00 00  43 45 56 00 

Then, simply concatenate your code with cat :

cat header.cev mycode.bin > newimage.cev

At this point, you  have a good image, but with incorrect CRC. To obtain the correct CRC, you just have to download this image to the router with tftp, and it will tells you the good CRC. Copy/paste to your image using an hex editor.

Checking new image ... failed: CRC-error (0x042b49b7 <> 0xd90a573a)

I compiled U-boot after changing TEXT_START to offset 0x05FB0040 (I will explain how to do that), and tried to boot it. See next post.

(Last edited by sebtx on 14 Nov 2016, 22:44)

To compile u-boot, I started from arv7519rw board, and modified the generic vrx200 config file (arch/mips/include/asm/arch-vrx200/config.h)

I compiled U-boot-ram to avoid some lowlevel initialization.

You have to redefine the memory layout :

#if defined(CONFIG_SYS_BOOT_RAM)
#define CONFIG_SYS_TEXT_BASE            0x5FB0040 // Was 0xA0100000
#define CONFIG_SKIP_LOWLEVEL_INIT
#define CONFIG_SYS_DISABLE_CACHE
#endif

After that, you can put u-boot.img at offset 0x40 and try to boot it !

Starting file transfer ...OK (125668 bytes received)

Now, it's time to build flashable firmware.

Decided flash layout :

4 MB for kernel
26,75 MB for rootfs

EDIT : OK I found the reason. You have to disable this config option to have normal processor speed :

#define CONFIG_SYS_DISABLE_CACHE

It's a particularity of U-boot-RAM.
