From 1cc03c5c53c06a904ff1cea325e0202ab6313ee4 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 25 Aug 2014 11:07:28 +0200 Subject: dfu: Provide means to find difference between dfu-util -e and -R This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski Reviewed-by: Stephen Warren Tested-by: Stephen Warren --- include/dfu.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'include/dfu.h') diff --git a/include/dfu.h b/include/dfu.h index 7e0a99908c..f1a71c7902 100644 --- a/include/dfu.h +++ b/include/dfu.h @@ -150,11 +150,14 @@ struct dfu_entity *dfu_get_entity(int alt); char *dfu_extract_token(char** e, int *n); void dfu_trigger_reset(void); int dfu_get_alt(char *name); -bool dfu_reset(void); +bool dfu_detach(void); +void dfu_trigger_detach(void); +void dfu_clear_detach(void); int dfu_init_env_entities(char *interface, char *devstr); unsigned char *dfu_get_buf(struct dfu_entity *dfu); unsigned char *dfu_free_buf(void); unsigned long dfu_get_buf_size(void); +bool dfu_usb_get_reset(void); int dfu_read(struct dfu_entity *de, void *buf, int size, int blk_seq_num); int dfu_write(struct dfu_entity *de, void *buf, int size, int blk_seq_num); -- cgit v1.2.3
