Is your board supporting device tree? And the 0 shall be adjustable -
so others could re-use it.

[PATCH v2 2/7] f_sdp: Add high speed endpoint descriptor

[Peng Fan]

From: Ye Li <ye.li@nxp.com>

Add HS endpoint descriptor for SDP. So that we can use high speed endpoint,
and the SDP device can send packet with 512 byte size.

Do you use uuu for it? On which board do you perform tests?

[PATCH v2 3/7] f_sdp: Fix wrong usb request size

[Peng Fan]

From: Ye Li <ye.li@nxp.com>

Because the buffer length of sdp usb request is 65, we have to allocate
65 bytes not 64 bytes. Otherwise there is potential buffer overflow.

[PATCH v2 4/7] f_sdp: Support searching and loading FIT or container image

[Peng Fan]

Add support to f_sdp to search and load iMX8 container image or iMX8M
FIT image by new UUU command SDPV.

When using the SDPV, the uuu will continue to send out data after first
level boot loader used by ROM. This means uuu won't skip to the offset
of the second boot loader, and the padding data before second boot loader
will be sent out. So we have to search the FIT header or container header
in the buffer that SDP received.

Also change to more common method to exit f_sdp handler not depending on
SPL_FIT_FOUND flag because container loader won't set this.

Please correct me if I'm wrong, but is there any documentation entry on
using uuu with i.MX8* and this feature? If not - I would be very
grateful if you could add a good tutorial/explanation for it.

(as I personally use uuu for iMX28 and iMX6Q).

Thanks in advance.

uuu code is here: https://github.com/NXPmicro/mfgtools 

It has documentation on using it.

For i.MX8*, the major stuff is just uuu only support flash.bin which is packed
by imx-mkimage. For using upstream U-Boot to generate flash.bin, there
are still features not ported.

What kind documentation do you expect?

There are still lots stuff in downstream.. I am trying to upstream every bit
to make it work, but without usb in upstream, it would not work.

Thanks,
Peng.

Ok. So support to mkimage is not yet added.

Ok.

I would like to have documentation entries being added with every bit
of code ported from downstream to upstream.

As I do know that it is very handy to have it around - not in NXP's
forum or webpage, which can disappear - like pdfs for i.MX28.

Great :-)

Ok.

[PATCH v2 5/7] spl: add g_dnl_get_board_bcd_device_number

[Peng Fan]

Add g_dnl_get_board_bcd_device_number, the new BCD value is used by uuu to distinguish
if the SPL supports the SDPV.

[PATCH v2 6/7] f_sdp: Add EP1_OUT as default data receive pipe in sdp

[Peng Fan]

From: Sherry Sun <sherry.sun@nxp.com>

EP0 has been used to transfer file data in sdp before, but the max
packetsize of ep0 is 64 bytes. So in order to improve the file transfer
speed, here add the EP1_OUT interrupt endpoint which max packetsize is
set to 1024 byte.

After testing, it turns out that using ep1out is twice as fast as using
ep0 while receiving data in sdp.

[PATCH v2 7/7] f_sdp: Change bInterval of interrupt endpoint to 3

[Peng Fan]

From: Sherry Sun <sherry.sun@nxp.com>

Since the USB HID limits the maximum bandwidth(3072) for interrupt
endpoint transfers, when the bInterval set to 1, we can only support 3
boards to run sdp at the same time. In order to support more boards,
change the bInterval of interrupt endpoint to 3, which will not affect
the transmission speed.
