While updating the firmware of MC60 module with QFlash_V5.0, we are seeing one or other of following errors. The error goes away after multiple retrying - when powering
off the device and trying flashing again with same setting, it fails with ERR_2004_S_BROM_DOWNLOAD_DA_FAIL error. Again powering off the device, and flashing again shows ERR_2004_S_BROM_DOWNLOAD_DA_FAIL error. On third trial for flashing with same settings, the upgrade works many times. But its very painstaking to require multiple trial of re-flashing. What could be the reasons for these errors?
