TDA4VM: J7- TDA4EVM Fastboot support

Hi Gokul,

Couple of questions:

1) Are you referring to specific SDK version?
2) Do you mean Android fast boot?

Hi Keerthy,

1) Are you referring to specific SDK version? No. I am asking in generic for TDA4EVM   platform.
2) Do you mean Android fast boot? Yes,  the same mechanism but for flashing qnx ifs image and bootloader files  in the TDA4EVM board.

Gokul,

1. Is there any specific fastboot features you are planning to use ?

2. Do you have a preference of Fastboot over { Ethernet/USB ?}

Hi Praneeth,

1. We need to use for flashing/updating new images.(qns-ifs, testdata ,stage(bin/.libs) and bootloader files) as  mentioned in psdkqa user guide

https://www.ti.com/securesoftware/docs/autopagepreview.tsp?opnId=24427

PSDKQA Release 7Q70.1.3

2. we prefer it over USB.

Gokul

And Reference Android fastboot script is at :

Hi Praneeth,

Can you please share your email id? I would like to have a discussion on this.

Hi Praneeth,

I understood it will work for Android Platform. Have you tried this for Linux platform  ? (bootloader, kernel image & rootfs)..

What   will be challenges to make it work for QNX  platform ?

Gokul

Did not try on non android use case.

Fast boot is a flashing fwk,so I don't see a reason why it will not work for other os.

For linux ,dfu util is used for similar flashing purpose.

Hi Gokul,

For functionality that is equivalent to fastboot for Android, dfu ro Linux recommending contacting QNX.

Hi Keerthy,

I am trying to enter fastboot mode via the following command. I have connected the USB cable. 

What may be the problem to show the below one ?

=>fastboot 0

No USB device found

USB init failed: -19

Gokul,

1. what is the dip switch setting you are using ? I am using: SW3:1101001010, SW8: 10000000 SW9:00000000

2. is your linux machine detecting board when a usb cable is connected ? 

Hi Praneeth,

I am keeping SW8 & SW9 for SD card boot mode as mentioned.

Do i need to modify this settings ?

Gokul,

the url you mentioned is for rtos evm setup. I dont know or can comment on that information based on rtos boot media supported and the boot flow.

Fastboot is setup to flash images to eMMC UDA mode. The dip switch settings mentioned are for

1. Setting up eMMC UDA mode ( If a SD card is detected that gets the higher precedence for booting)

2. SW3: configures USB in gadget mode and this is needed for fastboot.

Give it a try

Praneeth,

I have tried . But it is not working.

I have configured SW3 as mentioned by you and configured sw8 & sw9 for SD-card as below,

http://downloads.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/psdk_rtos_auto/docs/user_guide/evm_setup_j721e.html

Is it possibe to get the  fastboot solution for this  case?

Gokul
