Boot failure for images less than size 8k over SPI

Revision(s) Affected

IWRL6432W ES2.1

Details

The EDMA address linking is not done in few cases (during SPI continuous download), due to which boot will fail over SPI continuous download image for the particular metaimage size ranges mentioned in the below table:

Image Size (Bytes) Issue Present
<2048 No
>2048 & <4096 No
>=4096 & <6144 Yes
>=6144 & <8192 Yes
>=8192 No

Workaround

Use image >8KB for boot over SPI. In case of lower image size, constant data will be appended during compile time to create an image >8 KB.
