Hi Tom,
Hi Pantelis,
usbdescriptors.h conflicts with linux/usb/ch9.h Remove it.
After rebasing on u-boot-usb/next below comment apply:
After applying this patch, I cannot build trats target anymore.
With u-boot-usb/master I can compile the u-boot for trats board with no warnings and errors.
Unfortunately after flashing with dfu, the u-boot is _NOT_ working properly anymore. It seems, that some parts of the binary weren't correct.
Are you writing to a file in a filesystem? I.e. FAT?
I'm in the middle of doing more extensive tests, but file write to an FS might have problems. I am using the raw mmc interface.
I've written u-boot to RAW eMMC (based on the LBA addressing). Moreover I was also able to write data to FAT and EXT4 fs (which uses standard fat/ext4 load commands).
There could be something there that it's missed. I'm in the middle of doing more extensive tests.
It writes u-boot.bin, but in a way that the board is bricked after flashing.
I need some time to perform the thorough review of core DFU patches (patches 7/10, 09/10, 10/10).
OK.
BTW:
- What is your target device? What is the output of dfu mmc 0 list
command on your device?
I'm on am335x_evm target, actual board is a beaglebone.
On trats it is: DFU alt settings list: dev: eMMC alt: 0 name: u-boot layout: RAW_ADDR dev: eMMC alt: 1 name: uImage layout: FAT
# setenv dfu_alt_info 'test part 0 3' # mmc part U-Boot# mmc part
Partition Map for MMC device 0 -- Partition Type: DOS
Part Start Sector Num Sectors UUID Type 1 63 112392 7a348599-01 0c Boot 2 112455 7501331 7a348599-02 83 3 7613786 12966 7a348599-03 83 # dfu mmc 0 list DFU alt settings list: dev: eMMC alt: 0 name: test layout: RAW_ADDR
Off topic: It would be nice to have all partitions listed with dfu mmc 0 list :-) and then have access to it via dfu-util tool (as a separate alt settings). But this is a task for the future :-).
Are you downloading u-boot.bin to the raw nand? I.e. there's no boot partition?
Yes, there isn't any partition for u-boot. I write to raw eMMC address.
All my tests have been downloading a small ext3 image to the mmc. I'm in the middle of doing more extensive tests but those takes a huge amount of time... :(
This is because of very low DFU transmission speed (It uses only EP0 with EPS=64B , so it is meant to transfer really small files).
Updating rootfs via DFU would take much time. It is OK, to transfer u-boot, uImage, some log data.
- Please look into the TRATS board (especially the CONFIG_DFU_ALT
constant) for reference.
Already looked there.
- What is yours dfu-util version? (Mine is 0.1+svnexported)
