      What OS are you running?

Are you certain that the SA core is treating data accesses to the CSR range
data as non-cacheable and non-bufferable?

Try writting the address again prior to the read.
csrWrite(CSR, USTORE_ADDR, addr);       // Set the target address
    csrWrite(CSR, USTORE_DATA, 0xD8100020); // Write an instruction
    csrWrite(CSR, USTORE_ADDR, addr);       // Set the target address
AGAIN
<==
    result = csrRead(CSR, USTORE_DATA);
