It is +not capable of flashing firmware to a device, but can be used to +download firmware that is then capable of flashing. For example in +ChromeOS tegrarcm is used to download a special build of u-boot to the +target Tegra device with a payload that it then flashes to the boot +device. + +Platforms supported: +-Tegra20 +-Tegra30 + +How to use: +- Connect a USB cable from your development system to your Tegra +device. You will either need a USB A to A cable or A to micro B +depending on the target board. +- Find the appropriate BCT file for your board. For reference boards, +BCT files can be found in the L4T distribution from NVIDIA. +- Build some firmware for your device (such as u-boot) +- Run tegrarcm to download the firmware + +Example to download u-boot firmware to a Tegra20 seaboard: + +$ sudo tegrarcm --bct seaboard.bct --bootloader u-boot.bin --loadaddr 0x108000 +bct file: seaboard.bct +booloader file: u-boot.bin +load addr 0x108000 +entry addr 0x108000 +device id: 0x7820 +uid: 0x33c20c0413fb217 +RCM version: 2.1 +downloading miniloader to target... +miniloader downloaded successfully +Chip UID: 0x33c20c0413fb217 +Chip ID: 0x20 +Chip ID Major Version: 0x1 +Chip ID Minor Version: 0x4 +Chip SKU: 0x18 (t25) +Boot ROM Version: 0x1 +Boot Device: 0x3 (SPI) +Operating Mode: 0x3 (developer mode) +Device Config Strap: 0x0 +Device Config Fuse: 0x0 +SDRAM Config Strap: 0x0 +sending file: seaboard.bct +- 4080/4080 bytes sent +seaboard.bct sent successfully +sending file: u-boot.bin +- 268314/268314 bytes sent +u-boot.bin sent successfully + + +Changes: +V1.1 - Added this README file and automake fixes from Mike Frysinger + <vapier@gentoo.org> +V1.0 - Initial release |
