Thanks for the reply, colleague!
Hi, i think the structure of emmc is:
Astro 320 Hwid:1339
Regions Found: 10
Region Offset Size
------ ------ ----
(0x2b) 43, 0x00000000, 0x00010000 X-Loader
(0x05) 5, 0x00010000, 0x00040000 U-Boot
(0x10) 16, 0x00050000, 0x00100000 Logo
(0x22) 34, 0x00150000, 0x00020000
(0x29) 41, 0x00170000, 0x00440000 NV (non-vol memory region)
(0x5b) 91, 0x005b0000, 0x000c0000
(0x2d) 45, 0x00670000, 0x00020000
(0x0e) 14, 0x00690000, 0x00900000 Firmware
(0x53) 83, 0x02300000, 0x00000000 Filesystem (Fat32)
(0x30) 48, 0x02300000, 0x00000000 Filesystem (Fat32) Virtual?

The most important regions are the first two and the NV.
If these regions are corrupt you can not turn on the GPS, nor update it.

Make a backup of the emmc memory and maybe I can confirm this.
Some gps models have the important regions in a Nand memory and the filesystem in the emmc, but they are few cases, such as the Etrex20 / 30.
You can also post a photo of the pcb board and so we can see if there is any memory nand or just emmc.
If it is the case that only one emmc takes, the problem could be that emmc is damaged, but you could replace it with another equal or larger, with a backup of another that works (same gps model).

Unfortunately the creators of easyjtag do not give much support to Garmin GPS, it's a shame, because there is a lot of information to do it.
A greeting.
