When running sandbox, the following phases occur, each with different
malloc implementations or behaviors:
1) Dynamic linker execution, using the dynamic linker's own malloc()
implementation. This is fully functional.
2) After U-Boot's malloc symbol has been hooked into the GOT, but before
any U-Boot code has run. This phase is entirely non-functional, since
U-Boot's gd symbol is NULL and U-Boot's initf_malloc() and
mem_malloc_init() have not been called.
At least on Ubuntu Xenial, the dynamic linker does make both malloc() and
free() calls during this phase. Currently these free() calls crash since
they dereference gd, which is NULL.
U-Boot itself makes no use of malloc() during this phase.
3) U-Boot execution after gd is set and initf_malloc() has been called.
This is fully functional, albeit via a very simple malloc()
implementation.
4) U-Boot execution after mem_malloc_init() has been called. This is fully
functional with a complete malloc() implementation.
Furthermore, if code that called malloc() during phase 1 calls free() in
phase 3 or later, it is likely that heap corruption will occur, since
U-Boot's malloc implementation will assume the pointer is part of its own
heap, although it isn't. I have not actively observed this happening.
To prevent phase 2 from happening, this patch makes all of U-Boot's malloc
library public symbols have hidden visibility. This prevents them from
being hooked into the GOT, so only code in the U-Boot binary itself
actually calls them; any other code will call into the standard C library
malloc(). This also avoids the "furthermore" issue mentioned above.
I have seen references to this GCC pragma in blog posts from 2008, and
RHEL5's ancient gcc appears to accept it fine, so I believe it's quite
safe to use it without checking gcc version.

=> env set partitions $partitions_android
=> env save
After those operations one can go to fastboot mode and perform

During boot, U-Boot raises the CPU frequency but the CORE and MPU regulators
are not updated. This is not a problem in cold boot since the default values
that the pmic outputs are correct, but if Linux were to switch the module to a
low power OPP, the new voltage values will be retained after a reboot and the
module will likely hang once U-Boot raises the CPU frequency back up.

As tested on the Odroid XU3, large files to be stored on the file system
require considerable time to be physically written to the medium.
The default 300 ms is not enough to store large file (e.g. 26 MiB).
To fix this situation the DFU_MANIFEST_POLL_TIMEOUT has been defined.
It is used to cease the communication with dfu-util and allow the target
board to store the data on file system.
Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
This patch fixes situation when one would like to write large file into
medium with the file system (fat, ext4, etc).
This change sets file size limitation to the DFU internal buffer size.
Since u-boot is not supporting interrupts and seek on file systems, it
becomes challenging to store large file appropriately.
To reproduce this error - create large file (around 26 MiB) and sent it
to the target board.
Lets examine the flow of USB transactions:
0. DFU uses EP0 with 64B MPS [Max Packet Size]
1. Send file - OUT (PC->target) - dat_26MiB.img is sent with 4096 B transactions
2. Get status - OUT (PC->target) - wait for DFU_STATE_dfuDNLOAD_IDLE (0x05) sent
from target board - IN transaction
(target->PC)
3. The whole file content is sent to target - OUT (PC->target) with ZLP [Zero
Length Packet]
Now the interesting part starts:
4. OUT (PC->target) Setup transaction (request to share DFU state)
5. IN (target->PC) - reply the current DFU state
- In the UDC driver the req->completion (with dfu_flush) is called
after successful IN transfer.
- The dfu_flush() (called from req->completion callback) saves the
whole file at once (u-boot doesn't support seek on fs).
Such operation takes considerable time. When the file
is large - e.g. 26MiB - this time may be more than 5 seconds.
6. OUT (PC->target) - ZLP, is send in the same time when dfu_flush()
writes data to eMMC memory.
The dfu-util application has hard coded timeout on USB transaction
completion set to 5 seconds (it uses libusb calls).
When the file to store is large (e.g. 26 MiB) the time needed to write it
may excess the dfu-util timeout and following error message will be displayed:
"unable to read DFU status" on the HOST PC console.
This change is supposed to leverage DFU's part responsible for storing files
on file systems. Other DFU operations - i.e. raw/partition write to NAND and
eMMC should work as before.
The only functional change is the error reporting. When dfu_flush() fails
the u-boot prompt will exit with error information and dfu-util application
exits afterwards as well.
Test HW:
- Odroid XU3 (Exynos5433) - test with large file
- Trats (Exynos4210) - test for regression - eMMC, raw,
