2. BRIEF DESCRIPTION
This User's Manual describes the hardware of the TQMLS1028A revision 02xx, and refers to some software settings.
Differences to TQMLS1028A revision 01xx are noted, when applicable.
A certain TQMLS1028A derivative does not necessarily provide all features described in this User's Manual.
This User's Manual does also not replace the NXP CPU Reference Manuals.
The information provided in this User's Manual is only valid in connection with the tailored boot loader,
which is preinstalled on the TQMLS1028A, and the BSP provided by TQ-Systems GmbH. See also chapter 6.
The TQMLS1028A is a universal Minimodule based on the NXP Layerscape CPUs LS1028A / LS1018A / LS1027A / LS1017A.
These Layerscape CPUs feature a Single, or a Dual Cortex®-A72 core, with QorIQ technology.
The TQMLS1028A extends the TQ-Systems GmbH product range and offers an outstanding computing performance.
A suitable CPU derivative (LS1028A / LS1018A / LS1027A / LS1017A) can be selected for each requirement.
All essential CPU pins are routed to the TQMLS1028A connectors.
There are therefore no restrictions for customers using the TQMLS1028A with respect to an integrated customised design.
Furthermore all components required for the correct CPU operation, like DDR4 SDRAM, eMMC, power supply and power
management are integrated on the TQMLS1028A. The main TQMLS1028A characteristics are:
•CPU derivatives LS1028A / LS1018A / LS1027A / LS1017A
•DDR4 SDRAM, ECC as an assembly option
•eMMC NAND Flash
•QSPI NOR Flash
•Single supply voltage 5 V
•RTC / EEPROM / temperature sensor
The MBLS1028A also serves as carrier board and reference platform for the TQMLS1028A.

4.2.2 Self-Reset on TQMLS1028A revision 01xx
The following block diagram shows the RESET_REQ# / RESIN# wiring of the TQMLS1028A revision 01xx.
Figure 7: Block diagram RESET_REQ# / RESIN# TQMLS1028A revision 01xx
4.2.3 Self-Reset on TQMLS1028A revision 02xx
The LS1028A can initiate or request a hardware reset via software.
The output HRESET_REQ# is driven internally by the CPU and can be set by software by writing to RSTCR register (bit 30).
By default, RESET_REQ# is fed back via 10 kΩ to RESIN# on the TQMLS1028A. No feedback on the carrier board is required.
This leads to a self reset when RESET_REQ# is set.
Depending on the design of the feedback on the carrier board, it can "overwrite" the TQMLS1028A internal feedback and thus,
if RESET_REQ# is active, can optionally
•trigger a reset
•not trigger a reset
•trigger further actions on the base board in addition to the reset
RESET_REQ# is indirectly routed as signal RESET_REQ_OUT# to the connector (see Table 4).
"Devices" that can trigger a RESET_REQ# see TQMLS1028A Reference Manual (3), section 4.8.3.

4.3.3 Reset Configuration Word
The RCW structure (Reset Configuration Word) can be found in the NXP LS1028A Reference Manual (3).
The Reset Configuration Word (RCW) is transferred to the LS1028A as memory structure.
It has the same format as the Pre-Boot Loader (PBL). It has a start identifier and a CRC.
The Reset Configuration Word contains 1024 bits (128 bytes user data (memory image))
+ 4 bytes preamble
+ 4 bytes address
+ 8 bytes end command incl. CRC
= 144 bytes
NXP offers a free tool (registration required) "QorIQ Configuration and Validation Suite 4.2" with which the RCW can be created.
Note: Adaption of RCW
The RCW must be adapted to the actual application. This applies, for example, to SerDes configuration
and I/O multiplexing. For the MBLS1028A there are three RCWs according to the selected boot source:
-rcw_1300_emmc.bin
-rcw_1300_sd.bin
-rcw_1300_spi_nor.bin
4.3.4 Settings via Pre-Boot-Loader PBL
In addition to the Reset Configuration Word, the PBL offers a further possibility to configure the LS1028A without any additional
software. The PBL uses the same data structure as the RCW or extends it. For details see (3), Table 19.
4.3.5 Error handling during RCW loading
If an error occurs while loading the RCW or the PBL, the LS1028A proceeds as follows, see (3), Table 12:
Halt the Reset Sequence on RCW Error Detection.
If the Service Processor reports an error during its process of loading the RCW data, the following occurs:
•The device reset sequence is halted, remaining in this state.
•An error code is reported by the SP in RCW_COMPLETION[ERR_CODE].
•A request for a reset of the SoC is captured in RSTRQSR1[SP_RR], which generates a reset request if not masked by
RSTRQMR1[SP_MSK].
This state can only be exited with a PORESET_B or Hard Reset.
4.4 System Controller
The TQMLS1028A uses a system controller for housekeeping and initialization functions. This system controller also performs
power sequencing and voltage monitoring.
The functions are in detail:
•Correctly timed output of the reset configuration signal cfg_rcw_src[0:3]
•- Input for cfg_rcw_src selection, analogue level to encode five states (see Table 7):
1. SD card
2. eMMC
3. NOR Flash
4. Hard-coded
5. I2C
•Power Sequencing: Control of power-up sequence of all module-internal supply voltages
•Voltage supervision: Monitoring of all supply voltages (assembly option)

4.5 System Clock
The system clock is permanently set to 100 MHz. Spread spectrum clocking is not possible.
4.6 SDRAM
1, 2, 4 or 8 GB of DDR4-1600 SDRAM can be assembled on the TQMLS1028A.
4.7 Flash
Assembled on TQMLS1028A:
•QSPI NOR Flash
•eMMC NAND Flash, Configuration as SLC is possible (higher reliability, half capacity)
Please contact TQ-Support for more details.
External storage device:
•SD card (on MBLS1028A)
4.7.1 QSPI NOR Flash
The TQMLS1028A supports three different configurations, see following Figure.
1. Quad SPI on Pos. 1 or Pos. 1 and 2, Data on DAT[3:0], separate chip selects, common clock
2. Octal SPI on pos. 1 or pos. 1 and 2, Data on DAT[7:0], separate chip selects, common clock
3. Twin-Quad SPI on pos. 1, Data on DAT[3:0] and DAT[7:4], separate chip selects, common clock

4.7.2 eMMC / SD card
The LS1028A provides two SDHCs; one is for SD cards (with switchable I/O voltage) and the other is for the internal eMMC (fixed
I/O voltage). When populated, the TQMLS1028A internal eMMC is connected to SDHC2. The maximum transfer rate corresponds
to the HS400 mode (eMMC from 5.0). In case the eMMC is not populated, an external eMMC can be connected.

4.8 EEPROM
4.8.1 Data EEPROM 24LC256T
The EEPROM is empty on delivery.
•256 Kbit or not assembled
•3 decoded address lines
•Connected to I2C controller 1 of the LS1028A
•400 kHz I2C clock
•Device address is 0x57 / 101 0111b
4.8.2 Configuration EEPROM SE97B
The temperature sensor SE97BTP also contains a 2 Kbit (256 × 8 Bit) EEPROM. The EEPROM is divided into two parts.
The lower 128 bytes (address 00h to 7Fh) can be Permanent Write Protected (PWP) or Reversible Write Protected (RWP) by
software. The upper 128 bytes (address 80h to FFh) are not write protected and can be used for general purpose data storage.
Figure 10: Memory Map SE97BTP EEPROM
The EEPROM can be accessed with the following two I2C addresses.
•EEPROM (Normal Mode): 0x50 / 101 0000b
•EEPROM (Protected Mode): 0x30 / 011 0000b
The configuration EEPROM contains a standard reset configuration at delivery.
The following table lists the parameters stored in the configuration EEPROM.
Table 8: EEPROM, TQMLS1028A-specific data

The configuration EEPROM is only one of several options for storing the reset configuration.
By means of the standard reset configuration in the EEPROM, a correctly configured system can always be achieved by simply
changing the Reset Configuration Source.
If the Reset Configuration Source is selected accordingly, 4 + 4 + 64 + 8 bytes = 80 bytes are required for the reset configuration.
It can also be used for the Pre-Boot Loader PBL.
