U-Boot FASTBOOT flash commands for NOR storage

radikedalpatadu — Fri, 15 Jul 2016 10:52:09 GMT

Hi All,

I would like to know whether it is possible to use fastboot flash/erase commands for a NOR storage. I am using an imx6 processor together with a NOR storage.

Currently "rx_process_flash" function in "cmd_fastboot.c" file supports three storage types.

CONFIG_FASTBOOT_STORAGE_MMC

CONFIG_FASTBOOT_STORAGE_NAND

CONFIG_FASTBOOT_STORAGE_SATA

However, there is no CONFIG type for NOR storage. Sending a fastboot flash command from the host machine result in the following response from the U-Boot console.

Not support flash command for current device 0

send: FAILfailed to flash device

Does fastboot provides support for NOR flash? What modifications do I need to do in order to in the U-Boot configuration file in-order to support fastboot for NOR storage?

Best Regards,

Radike

Hello Radikedalpatadu,

As far as I know fastboot is not available for NOR storage, perhaps because NOR storage is not as fast as other media.

However, you should be able to customize the current code to adapt for NOR storage. Unfortunately there is not much documentation that allows to easily customize the fastboot code.

Regards,
