Ah :-( In November when I sent these patches, U-Boot binary was smaller. > The branch is https://github.com/lmajewski/u-boot-dfu/tree/testing > > Have you experienced similar issues? Yes, memory for U-Boot is limited. It is needed to decrease size of U-Boot binary and then it will work. I will try to look at it later and find some dead code which can be commented or removed to decrease binary size... If you have an idea what increased U-Boot side it could help. > > Pali Rohár (16): > > serial: usbtty: Fix puts function > > serial: usbtty: Send urb data in correct order > > usb: musb: Fix compilation of gadget code > > usb: musb: Always clear the data toggle bit when configuring ep > > usb: musb: Fix configuring FIFO for endpoints > > usb: musb: Read value of PERI_RXCSR to 16bit variable > > usb: musb: Fix transmission of bigger buffers > > usb: musb: Fix receiving of bigger buffers > > usb: musb: Fix handling interrupts for EP0 and SET ADDRESS commmand > > usb: musb: Ensure that we set musb dynamic FIFO buffer for every > > endpoint > > usb: gadget: Use dbg_ep0() macro instead of serial_printf() > > arm: omap3: Compile lowlevel_init() function only when it is used > > arm: omap3: Compile s_init() function only when it is used > > Nokia RX-51: Remove function set_muxconf_regs() > > Nokia RX-51: Move content of rx51.h to rx51.c > > Nokia RX-51: Enable usbtty serial console by default > > > > Makefile | 1 + > > arch/arm/mach-omap2/omap3/board.c | 3 + > > arch/arm/mach-omap2/omap3/lowlevel_init.S | 6 +- > > board/nokia/rx51/rx51.c | 28 +- > > board/nokia/rx51/rx51.h | 377 > > ---------------------- configs/nokia_rx51_defconfig | > > 7 +- doc/README.nokia_rx51 | 15 +- > > drivers/serial/usbtty.c | 16 +- > > drivers/usb/gadget/ep0.c | 16 +- > > drivers/usb/musb/musb_core.c | 12 +- > > drivers/usb/musb/musb_udc.c | 61 ++-- > > include/configs/nokia_rx51.h | 21 +- > > 12 files changed, 82 insertions(+), 481 deletions(-) > > delete mode 100644 board/nokia/rx51/rx51.h > > > > > > > Best regards, > > Lukasz Majewski > > -- > > DENX Software Engineering GmbH, Managing Director: Wolfgang Denk > HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany > Phone: (+49)-8142-66989-59 Fax: (+49)-8142-66989-80 Email: lu...@denx.de
