Hi,
currently I’m working with the GM02SP module its firmware is quite low (ue8.2.0.3) what is the proper upgrade path for this?
currently I’m pointing it to a https dup file specifically GP02RBAQ-DM_LR8.2.2.1-63493.dup it just gives me a “CME ERROR: generic error” response to a AT+SQNSUPGRADE request.
is there a way to use AT+SQNSUPGRADE that may be pointed to a HTTP request instead of HTTPS?
and if not how would i be able to do this over JTAG and are there any specific SDKs to use or specific devices recommended to ugrade locally?
Hi Brandon,
1\For local SW upgrade, you can leverage to Sequans SFU tool. The general kinds of upgrade mode are:
#1 SFU DUP upgrade: It is performed for full software upgrades, or with differential DUP softwares containing changes between the current and the new version.
#2 SFU RASTER upgrade: It is used to copy a full flash image to memory. All device settings are back to default.
NOTE: Do NOT interrupt SW upgrade procedure or device might bricked!!
2\ Here the upgrade path is from LR8.2.0.3 to LR8.2.2.1. It is quiet a gap of release history. So, it is recommended to run SFU raster upgrade to ensure device start with complete new SW baseline.
3\SFU raster SW upgrade procedure: I made brief slides to introduce the procedure in detail. Please reference to attachment for it.
