Troubleshooting

The trouble shooting given here comprises of hardware errors and input parameter error.

Comments

The inputs lowEnabledBlocks, midEnabledBlocks and highEnabledBlocks are bit-mapped

arguments that are used to select the blocks to be evaluated in the Low/Mid/High address

addrSeq

To determine the

address sequence to be

used during array

integrity checks.

The default sequence (addrSeq = 0) is meant to

replicate sequences normal “user” code follows,

and thoroughly check the read propagation paths.

This sequence is proprietary.

The alternative sequence (addrSeq = 1) is just

logically sequential.

It should be noted that the time to run a sequential

sequence is significantly shorter than the time to

run the proprietary sequence.

misrValue

A structure variable

containing the MISR

values calculated by the

user using the off-line

MISR generation tool.

The individual MISR words can range from

0x00000000 - 0xFFFFFFFF

CallBack

Address of void call back

function pointer.

Any addressable void function address. To disable

it use NULL_CALLBACK macro.

Returned error bits

Possible causes

Solution

C90FL_ERROR_AIC_MISMATCH

The MISR value calculated

by the user is incorrect.

Re-calculate the MISR values

using the correct Data and

addrSeq.

The MISR calculated by the

Hardware is incorrect.

Hardware Error.

C90FL_ERROR_AIC_NO_BLOCK

None of the Blocks are

enabled for Array Integrity

Check

Enable any of the blocks using

variables lowEnabledBlocks,

midEnabledBlocks and

highEnabledBlock.
