Oh, i see. I put pendrive into usb and sent command via RS232 ( I'm able to see fastboot.bin file by running "fatls usb 0:1")

fatload usb 0:1 0x1000000 fastboot.bin 0x60000

nand erase 0x0 0x60000

nand write 0x1000000 0x0 0x60000

I think commands are a bit similar to those from u-boot bootloader . I think you have to think twice before execute any commands, because calling wrong syntax is a shortest route to brick your tuner.

Smartest thing in my opinion is to use "HiTool-STB-5.0.6" for flashing by rs232 cable. Just make sure you choose Hi3798MV200 CPU for Zgemma H9S.

You may check what's going on by connecting to your box a simple rs232 cable. Pendrive should be formatted with fat32 filesystem and contains at the root : h9 dir, fastboot.bin file and bootargs.bin file. You have to put this pendrive into USB 2.0 slot, not USB3.0. Download firmware from http://images.mynonpublic.com/…/index.php?open=zgemmah9s for OpenATV.

Hi. I have a similar problem. Zgemma wants to read fastboot.bin only from USB drive. If I put on it fresh installable OpenATV image, then Zgemma flash it, reboot and again - read fastboot.bin from USB and flash tuner. It enter into loopback. I moved files from h9 dir to root dir of USB and then - Zgemma is booting. I put out pendrive - zgemma stops at :

Bootrom start

Boot Media: NAND

Enter usb bootstrap by flash

USB(1): no found "fastboot.bin".

Boot head format invalid.
Do you have any idea, how to force Zgemma H9S to load fastboot.bin from nand, not USB(1)?

Flashing fastboot manually from USB pendrive:

fatload usb 0:1 0x1000000 fastboot.bin 0x60000
nand erase 0x0 0x60000

nand write 0x1000000 0x0 0x60000

doesn't help either (fastboot.bin from newest OpenATV image)
