From uboot-rex/doc/README.android-fastboot:

Code:

The fastboot protocol requires a large memory buffer for downloads. This buffer should be as large as possible for a platform. The location of the
buffer and size are set with CONFIG_FASTBOOT_BUF_ADDR and
CONFIG_FASTBOOT_BUF_SIZE.

So, for the PW4, the size limitation for fastboot downloads is in uboot-rex/include/configs/mx6sll_rex_android.h

Code:

#define CONFIG_FASTBOOT_BUF_SIZE   0x1C000000l /* 448MB */

469 762 048 bytes, just enough to hold rootfs.img (460 800 000 bytes)

(OK, this does not solve the non-reporting of transfer errors)
