2021-06-08hexdump: Allow ctrl-c to interrupt outputSimon Glass1-4/+9
If a long hexdump is initated the user may wish to interrupt it. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-06-08hexdump: Support any rowsizeSimon Glass1-3/+9
At present print_hex_dump() only supports either 16- or 32-byte lines. With U-Boot we want to support any line length up to a maximum of 64. Update the function to support this, with 0 defaulting to 16, as with print_buffer(). Signed-off-by: Simon Glass <sjg@chromium.org>
2021-06-08hexdump: Add support for sandboxSimon Glass1-1/+4
The current implementation outputs an address as a pointer. Update the code to use an address instead, respecting the 32/64 nature of the CPU. Add some initial tests copied from print_test_display_buffer(), just the ones that can pass with the current implementation. Note that for this case print_hex_dump() and print_bufffer() produce the same result. For now the tests are duplicated sine we have separate functions. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-06-08hexdump: Move API to header fileSimon Glass1-75/+3
Move the comments to the header file so people can find the function info without digging in the implementation. Fix up the code style and add an enum for the first arg. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-04-24lib: do not provide hexdump in SPLHeinrich Schuchardt1-1/+1
SPL should not be enlarged by building with CONFIG_HEXDUMP=y. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Tom Rini <trini@konsulko.com>
2018-06-13lib: Add hexdumpAlexey Brodkin1-0/+245
Often during debugging session it's very interesting to see what data we were dealing with. For example what we write or read to/from memory or peripherals. This change introduces functions that allow to dump binary data with one simple function invocation like: ------------------->8---------------- print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len); ------------------->8---------------- which gives us the following: ------------------->8---------------- 00000000: f2 b7 c9 88 62 61 75 64 72 61 74 65 3d 31 31 35 ....baudrate=115 00000010: 32 30 30 00 62 6f 6f 74 61 72 67 73 3d 63 6f 6e 200.bootargs=con 00000020: 73 6f 6c 65 3d 74 74 79 53 33 2c 31 31 35 32 30 sole=ttyS3,11520 00000030: 30 6e 38 00 62 6f 6f 74 64 65 6c 61 79 3d 33 00 0n8.bootdelay=3. 00000040: 62 6f 6f 74 66 69 6c 65 3d 75 49 6d 61 67 65 00 bootfile=uImage. 00000050: 66 64 74 63 6f 6e 74 72 6f 6c 61 64 64 72 3d 39 fdtcontroladdr=9 00000060: 66 66 62 31 62 61 30 00 6c 6f 61 64 61 64 64 72 ffb1ba0.loadaddr 00000070: 3d 30 78 38 32 30 30 30 30 30 30 00 73 74 64 65 =0x82000000.stde 00000080: 72 72 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 rr=serial0@e0022 00000090: 30 30 30 00 73 74 64 69 6e 3d 73 65 72 69 61 6c 000.stdin=serial 000000a0: 30 40 65 30 30 32 32 30 30 30 00 73 74 64 6f 75 0@e0022000.stdou 000000b0: 74 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 30 t=serial0@e00220 000000c0: 30 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00.............. ... ------------------->8---------------- Source of hexdump.c was copied from Linux kernel v4.7-rc2.
