Hello, My organization has many EM7565 modules deployed already. We have encountered issues where the EM7565 gets stuck in the bootloader, which we have found is recoverable by reflashing the firmware, so we modified our software to perform this procedure for reliable operation of the EM7565. Howev…

It appears I have a workable automated solution, though it requires a software change I wanted to avoid. The solution is: When the EM7565 is in the bootloader (1199:9090), flash it When the EM7565 is in low power mode and AT!PCINFO? shows IMSWITCH=1, flash it I’m using 01.14.13.00_GENERIC FW+P…

have you tried the fwdwl tool here? https://source.sierrawireless.com/resources/airprime/software/mbpl/mbpl-software-latest/#sthash.ZXRwiiKx.dpbs

I just the updated to use the firmware downloader recommended. I was able to flash successfully once, but I cannot replicate it on another module (I have about 10 I can try on). It’s possible I ran some AT command but it’s really unclear to me what’s happening. I found that after flashing this sec…

You only download the nvu file, not the cwe file 01.14.02.00 for firmware How did you use the fwdwl tool?

as @jyijyi say, the key point is AT!IMAGE? result. You only store the 01.14.02.00_GENERIC PRI (nvu) file on the advice. when you try to switch to AT!IMPREF=“GENERIC” you got an error due lack of the 01.14.02.00 FW in the FW slots. The best practice is to reflash the GENERIC 01.14.02.00 from the s…

Thank you for the time @jyijyi and @elkanam . As you’ll find in the log below, I had already succesfully flashed the modem with both images using an archive provided from the above link, however only the PRI is listed and the firmware is not. Am I doing something wrong? I reproduced this error with …

Hi @mregan the flashing seen good, but your image is stored in slot 255 and not in the flash storage slots. [image] mregan: Active FW image is at slot 255 so you can re-flash it to see it in one of the FW slots.

@elkanam , Thank you. I can confirm I’ve recovered a couple of units this way. Do you know what is slot 255, or why the firmware isn’t being loaded into a proper slot upon flashing the first time? The Image Switching documentation doesn’t seem to have any information about this.

Going further down the rabbit hole: lite-fw/inc/lite-fw.h from MBPL_SDK_R35_ENG4-lite.bin.tar.gz has the following: /*! Non image switch type of firmware download */ eFWDWL_TYPE_REG_DWLD, // Non image switch scenario, plain switch to B&H mode (0x003E) My logs show: [20:57:46.11…
