ISD15D00/3800 trouble shooting manual

1 Description

This document describe troubleshooting steps and methods of ISD15D00 and ISD3800. User

can check problems with check list or reference the check steps of chapter3: VPE + Dongle +

Demo board.

2 Check list:

Environment1: VPE + Dongle + Demo board

①Check clock(3.2)：Check CLK CFG by VPE & check J9 Jumper* if use EXT_RES or XTAL

②Check CFG(3.1)

③Already burn device(3.4)?

Environment2: VPE + Dongle + User’s board with ISD15D00/3800

①Check clock(3.2)：Check CLK CFG by VPE & check crystal or resistor for EXT_RES

②Check CFG(3.1)

③Already burn device(3.4)?

Environment3: User’s MCU + Demo board

①Check SPI commands sequence(5.1) and reset signal

②Check SPI waveform by scope(3.6). Also check if SSB pull high after command.

③Already burn device(3.4)?

④Check clock(5.4)：Check CLK CFG & check J9 Jumper* if use EXT_RES or XTAL

⑤Check CFG(5.5)

⑥Check status byte(5.6)

General check: for any ISD3800 application environment

⑦Check if Flash is empty. Check system VMs: POI VM, PU VM and Wakeup VM. Check

Schematic.

⑧Understand timing

⑨Know how to unlock a device which is locked by bad flash content.

⑩Know how to solve the programming difficulty under certain configurations.

※J9’s printing “Ext_Res”and “XTAL”are reversed. Be careful Jumper’s position.

3 VPE + Dongle + Demo board:

Hardware：①Dongle：ISD-ES-MINI-USB

②Demo Board：ISD-DEMO3800 or ISD-DEMO15D00

③Speaker

Software：ISD-VPE15D00

Example project：C:\ProgramFiles\ISD-VPE15D00\ISD15D00example_1\ISD15D00example_1.prj

3.1 Check CFG : Check by VPE, click “Read CFG” at page “Configuration Registers”.

By example1：CFG02：0x48

CFG05：0x80

CFG18：0xAB

If need to modify CFG, type in value and click “Write CFG”.

※For detailed configuration register, reference Section 12.3 of design guide.

FAQ

3.2 Check Clock: Check by VPE, click “Read CLK CFG” at page “Audio Cmds”.

By example1：CLK CFG：0x34

Table 12-1 of Design Guide：Clock Configuration Register Description

Table 12-2：Clock Configuration source

※For detailed clock configuration, reference Section 12.1 of design guide.

3.3 Play Voice Prompt：choose a sound and click “Play to device”.

“Play to device”will transfer sound data through SPI to Demo board and play it immediately. It does

not play VP in Flash.

FAQ

3.4 Burn Device: will download .mem file into flash. Before executing SPI commands, be sure

already “Burn Device”.

Before “Burn Device”, execute “Create Programming File”and will generate .mem file. (Example1：

C:\Program Files\ISD-VPE15D00\ISD15D00example_1\ISD15D00example_1.mem)

FAQ

3.5 Execute by SPI commands:

①choose a VP and click “Play VP”.

②choose a VM and click “Execute VM”

Just send SPI commands but without sound data. Play VP and VM in Flash, programmed by “Burn

Device”before.

FAQ

2012.11 Ver.00

③“Send SPI Cmd”：With proper ①configuration and ②burn device and ③PU(Power Up), send

SPI command Play VP(0xA6) should be played.

By example1, to play VP of index C：A6000C

Section 13.1.1 of design guide：Play Voice Prompt

※For detailed SPI commands, reference Chapter 13 of design guide.

3.6 Check SPI waveform:

Measure waveforms of SCLK, SSB, MISO, MOSI.

FAQ

Waveform1 of whole 0xA6000C by 50us：

Check if SSB pull high after each command.

Waveform2 of detailed 0xA6000C by 10us：

MISO response：0x60 0x60 0x60
