Fastboot to flash file size bigger than 512MB

williamtung — Thu, 05 Sep 2013 03:28:16 GMT

Hi,

I verified the fastboot with a system.img (280MB) and confirmed it's working correctly (download and flash OK).

When I tried to use fastboot to flash the system.img (512MB), I saw two different errors:

1. FAILED (remote: data too large) on PC and send: FAILdata too large on iMX6

when I set

#define CONFIG_FASTBOOT_TRANSFER_BUF 0x2C000000

#define CONFIG_FASTBOOT_TRANSFER_BUF_SIZE 0x14000000 /* 320M byte */

I assumed it's because not enough transfer buffer and increased the size, but got #2 error below

2. FAILED (data transfer failure (Unknown error)), fastboot exits on PC and the iMX6 stuck on receiving data with 8~9 dots (.........)

When I set

#define CONFIG_FASTBOOT_TRANSFER_BUF 0x48000000

#define CONFIG_FASTBOOT_TRANSFER_BUF_SIZE 0x22000000 /* 320M byte */

Does anybody see the same failure before? Please help determine whether PC or iMX6 causes the problem. Thanks.

Please check the 4.1.1 Storage Partitions in the Android BSP User Guide. Double check if your image is exceeded the size of the defined partition or not.

Hi Jimmy,

Here is the partition definition in the mksdcard-android.sh.tar. The size of SYSTEM partition is 512MB.

#!/bin/sh

# partition size in MB

BOOTLOAD_RESERVE=8

BOOT_ROM_SIZE=8

SYSTEM_ROM_SIZE=512

DATA_SIZE=2048

CACHE_SIZE=512

RECOVERY_ROM_SIZE=8

VENDER_SIZE=8

MISC_SIZE=8

Is there a size limitation for fastboot to transfer?

So, have you try to change the size bigger?

Yiking,

I realize this is an old thread, but I would to reopen it. Are you aware of any patches to the fastboot source that will permit the uploading of data in chuncks to work around the limit discovered earlier in this thread. In particular, the userdata partition I work with is nearly 4.0 GB in size? Thank you.
