Guidance on sp9832e_1h10_gofu (Connected but receive 7e ver expected error)

[BenEdridge]

Hi there, great project.

I've attempted running spd_dump on Ubuntu 22.04 with configuration for a sp9832e_1h10_gofu device and using signed fdl1 and fdl2 obtained from a firmware dump but having issues.

I did the following:

1. Cloned and built the repo (Made sure to use libusb)
2. Ran spd_dump before boot mode
3. Removed charging cable
4. Held volume down and then inserted battery
5. Plugged charging cable back into device
6. Confirmed boot mode entered as below

usb 1-1: new full-speed USB device number 16 using xhci_hcd
usb 1-1: not running at top speed; connect to a high speed hub
usb 1-1: New USB device found, idVendor=1782, idProduct=4d00, bcdDevice=24.16
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: Gadget Serial
usb 1-1: Manufacturer: spreadtrum with musb-hdrc

When using spd_dump I get the following error:

./spd_dump \
	--verbose 2 \
	--wait 300 \
	keep_charge 1 \
	fdl fdl1-sign.bin 0x00005000 \

	blk_size 0x2000 \
	read_part logo 0 8M logo.bmp \
	power_off

send (1):
7e                                               |~|
ver expected

This is similar to an issue raised earlier in: https://github.com/ilyakurdyukov/spreadtrum_flash/issues/2 but the differences is that 7e appears to be related to the HDLC_HEADER. So my assumptions are that I'd need to modify the communications to the device or perhaps build a custom fdl that suits the device?

Any suggestions or help would be much appreciated. Thanks. I've also attached the BMA Configuration file obtained during a a flash.
