RTL8720DN GDMA some trouble

hi , When I use SPI in USI mode, sometimes GDMA is enabled, but the first 16 data is not received successfully but the subsequent data is received normally. What is causing this? Is the system delay caused by large?

Hi, please let us know on which platform are you developing? and if there is a version number?

SDK: ambd sdk QC-V1.0.0
