Hi everyone,
I'm trying to update the PN7462 EEPROM by USB Mass Storage Mode on linux, but it is not working.
I'm using mount command to mount it as flash driver, erasing DRP_<nn>.dat file, loading my user_ee.bin file into it, umounting the partition and pressing RST_N button. After that I upload my application (on linux as well) and it's not working.
If I update the EEPROM using Windows it works, even loading my application on linux.
Share the feedback from a customer who met the same issue on linux.
===============================================
The solution was change some configs in the computer, and use the “dd” cmd in the sector programmed instead of “cp” and “unmount” to copy files.
Following those steps:
1 – unload the module usb-storage, and cmd “modprobe usb-storage quirks=1fc9:0117:r,n,m”
2 – “dd if=pn/user_ee.bin of=/dev/sdc seek=03 (to copy the EEPROM)
There are several programmers with the same issue in the community, please, share with them
