Troubleshooting

Comments

The contents pointed by pFailLoc, pFailData and pFailSource are updated only when there

is a mismatch between the source and destination regions.

Assumptions

It assumes that the Flash block is initialized using a ‘FlashInit()’ API.

pFailAddress

Return first failing address in

Flash.

Only valid when the function returns

C90FL_ERROR_VERIFY.

pFailData

Returns first mismatch data

in Flash.

Only valid when this function returns

C90FL_ERROR_VERIFY.

pFailSource

Returns first mismatch data

in buffer.

Only valid when this function returns

C90FL_ERROR_VERIFY.

CallBack

Address of void call back

function pointer.

Any addressable void function address. To disable it

use NULL_CALLBACK macro.

C90FL_ERROR_RANGE

C90FL_ERROR_VERIFY

Table 20. Troubleshooting for ProgramVerify()

Returned error bits

Description

Solution

C90FL_ERROR_ALIGNMENT

This error indicates that

dest/size/source isn’t

properly aligned

Check if dest and size are aligned on

double word (64-bit) boundary. Check if

source is aligned on word boundary

C90FL_ERROR_RANGE

The area specified by

dest and size is out of

the valid C90FL address

range.

Check dest and dest+size, both should

fall in the same C90FL address ranges,

i.e. both in main array or both in shadow

row

C90FL_ERROR_VERIFY

The content in C90FL

and source data

mismatch.

Check the correct source and destination

addresses, erase the block and

reprogram data into Flash.
