1. Release Content
This document provides the Release Notes for RM520N-GL-AA. The current release includes the firmware package.
| Package | Version |
|---|---|
| Firmware | RM520NGLAAR01A08M4G_01.200.01.200 |
2. Matters Needing Attention
- [1] The firmware version lower than R01A05 needs to be upgraded to the R01A05 version through USB Firehose, and cannot be upgraded to A05 through FOTA; R01A05 and above the firmware versions can be directly upgraded through FOTA.
- [2] The new firmware version cannot be downgraded to versions released before RM520NGLAAR01A07M4G_01.200.01.200, otherwise the module will not be able to work normally.
- [3] To extend the service life of flash, the following operations should be avoided to be performed frequently: powering on/off the module, CFUN switching, SIM card hot swapping, dual-SIM switching, and repeated execution of NVM commands.
- [4] It is not recommended to directly modify the pre-set APN profiles. Please create an APN profile after the existed CID number. Suppose you modify the APN profile of IMS, SOS, etc. with added specific attributes, these attributes are hidden after modification, causing the profile to still be unavailable.
- [5] During the FOTA upgrade process, it is necessary to ensure the stable power supply of the module. If the power is disconnected during the upgrade, there is a small probability that the flash will be damaged.
- [6] M.2 module is encapsulated without SPI, and SLIC cannot be mounted on the module.
