To test `sys/log: optimize header read based on image hash`, use this block
immediately after the optimized read.
```
+ /* verify */
+ bytes_read = log_read(log, dptr, &ue_imghash[0],
LOG_BASE_ENTRY_HDR_SIZE, LOG_IMG_HASHLEN);
- if (bytes_read != LOG_IMG_HASHLEN) {
- return SYS_EIO;
- }
+ if (bytes_read != LOG_IMG_HASHLEN) {
+ return SYS_EIO;
}
+ if (memcmp(hdr->ue_imghash, &ue_imghash[0], LOG_IMG_HASHLEN) != 0) {
+ console_printf("imghash read optimization check failed");
+ return SYS_EIO;
+ }
```
