---+!! ATMT MP170 1GB DAB/MP3 player

%TOC%

---++ Status
Uploading the current [[LogikDaxPort][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  [[LogikDaxPort][Logic Dax]].

---++ Hardware

   * [[TelechipsInfo][Telechips]] TCC773L CPU - ARM946E-S CPU Core (4KB Cache, up to 120MHz)
   * Kwang Sung Electronics [[http://www.kse.com.hk/new/spec/AEBP-8.pdf][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:
<pre>
      R G  M1-RGB  B
      0YOOO1B-38-AO2
</pre>
   * Samsung K9K8G08U0A 1GB NAND Flash

---++Differences with the [[LogikDaxPort][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:
