Hello,
the USB bootloader mode of PN7462 under Windows works very well.
The disk labelled PN7462_AU appears and I can replace firmware both Flash and EEPROM.
But I cannot mount the disk under Linux (Ubuntu 18.04 and Raspberry Pi 3).
Dmesg attached:
Thanks @jarojuda!
Are the sectors directly applicable to dd's `seek=<START_SECTOR>` like the following??
# EEPROM
dd if=./DRP_00.DAT seek=03 count=7 of=/dev/sdX
# FLASH
dd if=./CRP_00.BIN seek=10 count=316 of=/dev/sda
It seems that the counts {7, 316} are wrong as well...
Best, Nick
Thanks for the quick response!
after applying "usb-storage quirks=1fc9:0117:r,n,m" seen here it works like a charm now.
Reading back as following works as well, for verifying reasons..
dd of=./DRP_00.DAT.read skip=3 count=7 if=/dev/sda
dd of=./CRP_00.DAT.read skip=10 count=316 if=/dev/sda
Best
Many thanks for the @jarojuda! I was able to see the PN7412 as a mass storage device in UBUNTU 20. We are using a i.MX 8M Nano in our project, and the main goal is to update the PN7412 thru the i.MX USB bus. I couldn't manage to make it work on i.MX with the same steps listed here. I'm sending the dmesg output in the attachments. You guys have any idea what might be missing?
