Nucleus Name
DS_FLASH_ChecksumProgram
Nucleus Number
503
Description
Check the checksum of the application partitions by recalculating and comparing partition
checksums
Technical
-
Determine the number of segments
-
Find the application in each segment and determine its checksum
-
Check whether the checksums stored match the newly calculated
Execution Time
6 seconds
User Input
None
Error
Number
Description
50300
The checksum is valid, the test succeeded
50301
The checksum is invalid
Example
DS:> 503
050300:
BootCode checksum is: 0xBABE5B6F, which is correct
Diagnostics checksum is : 0xBABEBAFF, which is correct
Download checksum is: 0xBABEEDBF, which is correct
Application checksum is : 0xBABE8EEC, which is correct
Test OK @
Nucleus Name
DS_FLASH_Read
Nucleus Number
502
Description
Read from a specific memory address in FLASH
Technical
-
Decode the user input and check the ranges and whether the address is aligned on 4
bytes
-
Read the data and return this to the user
Execution Time
Less than 1 seconds.
User Input
The location from which data must be read
( FLASH starts at address 0xB8000000 )
Error
Number
Description
50200
Reading the FLASH succeeded
50201
Reading the FLASH failed; Wrong user input
50202
Address is not dividable by 4
Example
DS:> 502 0xb8000000
050200: Value read = 0x3C08A000
Test OK @
