ATMT MP170 1GB DAB/MP3 player

Status

Uploading the current Logik Dax code in SVN to the ATMT with tcctool works just fine, the lcd works and buttons can be read out. Furthermore, I uploaded the Logic Dax firmware with tcctool - it booted, and due to the connected USB and lack of NAND (removed to select USB boot mode) went straight to saying MTP connected.

Introduction

As suspected, this appears to be very similar if not identical to the Logic Dax.

Hardware

• Telechips TCC773L CPU - ARM946E-S CPU Core (4KB Cache, up to 120MHz)
• Kwang Sung Electronics ARBP-8 DAB Module - contains an Integrant Technologies ITD3020 tuner and Telechips TCC320 decoder. This DAB module is only capable of receiving Band 3 (174-240MHz) broadcasts, not Band L (1452-1492MHz)
• LCD module (seems to have an SSD1815 controller). Has the following markings:

      R G  M1-RGB  B
      0YOOO1B-38-AO2

• Samsung K9K8G08U0A 1GB NAND Flash

Differences with the Logic Dax

I don't know if any of these are of any importance, but for completeness:

DAB module is KSM-AEBP000S-800 6255 00-D-0PbF and not KSM-AEBP000S-800 6184 D-0PbF. It also does not appear to have an antenna. I'm not currently in a DAB Band III country so I can't test reception. Board version is 3306 instead of 2106

LCD is 0YOOO1B-38-AO2 and not 0YOOO1B-38-MO2

Flash is K9K8G08U0A and not K9K8G08U0M. Board version is 3506 cf. 1906.

USB

Conecting to USB without the NAND board attached gives the following in lsusb:
