Broadcom Confidential and Proprietary
Options:
-v verbose level
10.13 sechksum
Command: sechksum
Description: Check/Update Serial NVRAM checksum
Syntax: sechksum
Options:
-v<DEC> verbose level (0,1) (def=1)
-y<DEC> Auto correct CRC (def=0)
-n<DEC> Do not auto correct CRC (def=0)
10.14 sedump
Command: sedump
Description: Dump NVRAM content to a file. The value stored at location 0xC in the
NVRAM is the starting address of the code that the chip loads and executes. The code
starting address is 0x200 for NVRAM pages aligned on 256 byte boundaries and 0x2F8 for
the Atmel device that has a NVRAM page size of 264. If “sedump” is used to generate an
image file for a NVRAM/EEPROM burner then “-a” should be used, for an Atmel device, if
one wants to preserve the 0x2F8 code starting address that is automatically translated to
0x200 by software without the “-a” option. More details can be found in application note
570X-AN700-R.
Syntax: sedump -f<string> [Len]
Options:
-a<string> no Atmel Flash address translation
-f<string> string is the filename
-l<DEC> length in decimal, use 0 for entire NVRAM image (def=8192)
-s skip crc checking for legacy bootcode
