You can use the following flasher-scripts to program various types of tags with the Tag-Flasher or AP-Flasher. The Tag-Flasher is the easiest to build; it uses only a Wemos S2-Mini or clone to program quite a few different tags. The tags below are the tags that can be programmed with this flasher.

ZBS243-based tags
nRF52-based tags
88MZ100-based tags
cc1110-based tags

This is the schematic for the flasher, including a pinout for the debug-header that is used by quite a few Solum tags. This flasher is also compatible with the OEPL-AP-Flasher jig/programming boards.

This is what it looks like with the wires connected. I've chosen to use 0.635mm pitch wires, to be able to use the jigs with the 1.27mm FDC connectors. After soldering, you can add a little bit of hot-glue to make sure they stay attached.

Tag - Flasher connections

R - required
O - optional

Flasher Pin	Cable Pin	ESP32-S2 Pin	ZBS	nRF	88mz100	CC1110
VCC	1	16, 17, 18, 21	R	R	R	R
CS	2	34	R
GND	3	GND	R	R	R	R
CLK	4	33	R	R		(DC) R
TXD	5	36	O	O	R
MISO	6	35	R	R		(DD) R
TEST	7	38
MOSI	8	37	R
RXD	9	40	O	O	R
RESET	10	39	R		O	R

Not all connections are required by all tags! If you want to solder fewer wires, skip the optional and unused ones.

Flashing the flasher

Clone the Tag_Flasher repo and open into PlatformIO. Choose the correct COM-port and hit 'Upload'. Also, the precompiled binaries are part of any release, and to make it even easier, you can use the web flasher on https://install.openepaperlink.de to even flash it without installing any extra software.

OEPL-Flasher.py

This script connects to the S2-mini's serial port and enables flashing to ZBS243 and nRF52811-based tags.

usage: OEPL-Flasher.py [-h] [-p PORT] [-f] [-i] [-n] [-z] [-c] [--internalap] [-e] [--altradio] [--pt] {read,write,autoflash,debug} [filename]

OpenEPaperLink Flasher for AP/Flasher board

positional arguments:
  {read,write,autoflash,debug}
                        Command to execute
  filename              Filename for read/write commands

options:
  -h, --help            show this help message and exit
  -p PORT, --port PORT  COM port to use
  -f, --flash           Write to the flash
  -i, --infopage        Write to the infopage/UICR
  -n, --nrf82511        nRF82511 programming
  -z, --zbs243          ZBS243 programming
  -c, --ccxxxx          CCxxxx programming
  --internalap          Selects the internal accesspoint port
  -e, --external        Selects the external(side) port
  --altradio            Selects the alternate radio port
  --pt, --passthrough   Enters serial passthrough for debug output after flashing

88MZ100-OEPL/Serial-Flasher.py

This script connects through a serial-TTL interface or OEPL - Tag_Flasher or AP-Flasher.

Example: COM1 read file.bin, or COM1 write file.bin, or COM1 write_flash file.bin
To create an OTA file use: img file.bin

Solum ZBS243-based

Use with the -z option for ZBS243. Autoflash is currently not implemented on the Tag_Flasher/S2 version.

python3 OEPL-Flasher.py -e -z -p COM31 read blaat.bin --flash --pt

Nordic nRF-based

Use with the -n option for nRF52811

python3 OEPL-Flasher.py -e -n -p COM31 read blaat.bin --flash --pt

Note: If something's gone wrong with the UICR partition on your nRF tag, you can use the nrf_uicr_mac_patcher.py tool to patch a known good UICR partition dump with the MAC address of your broken tag.

Marvell 88MZ100-based

Main article here.

The Tag-Flasher is used in serial passthrough-mode in order to flash the 88MZ100 with a modified flasher-script. A serial DTR/Reset line is used to reset the tag during the connection stage; this is however not strictly necessary! If you connect or reset the tag when prompted by the script, the flasher will work fine.

python3 .\88MZ100-OEPL-Flasher.py COM31 write_flash '0130c8144117.bin'

TI CC1110-based

Important

Tag flasher version 50 or later is required for CC1110 support.

Use with the -c option for CC1110.

The CC1110 does not have an infopage nor is the Tag's EEPROM accessable. Autoflash is currently not implemented for the CC1110.

python3 OEPL-Flasher.py -e -c -p COM31 read blaat.bin --flash

See this page on the Wiki for additional information.

EFR32-based

This flasher does NOT support tags based on the EFR32. See the wiki for information on how to flash those.
