Title | TE0720 CPLD Firmware Revision Ugrade from REV05 to REV06 |
Subject | CPLD Firmware Revision Ugrade from REV05 to REV06 |
Issue Date | 2021-02-17 |
Products Affected
This change affects Trenz Electronic boards TE0720 of Revision 03: TE0720-03-*
Changes
#1 Added generic options for PUDC and Boot Mode
Type: Enhancement
Reason: Pullup or pulldown for IO pins selectable to change the boot mode and PUDC for custom request easier.
Impact: None. Default CPLD source code is still PUDC low (Zynq pullups activated) and Boot Mode QSPI/SD.
#2 MIO7 Pullnone
Type: Enhancement
Reason: HW Pulldown on carrier for Bank0 Voltage selection (3.3V)
Impact: None.
#3 Adding internal en_3v3_int
Type: Enhancement
Reason: To connect 3.3V to enable pin of the 3.3V regulator after the core
Impact: To achive power sequencing correctly
#4 JTAG C_* high impedance until 3.3VOUT can be high
Type: Enhancement
Reason: JTAG pins connected to Zynq are high impedance as long as the core voltage is not available.
Impact: No Impact, improve Power sequencing
#5 Boot mode pins are GND or high impedance until en_3v3_int are high
Type: Enhancement
Reason: Boot Mode pins connected to Zynq are high impedance as long as the core voltage is not available.
Impact: No Impact, improve Power sequencing
#6 MIO14,15 high impedance until en_3v3_int are high
Type: Enhancement
Reason: UART pins that to Zynq connected are high impedance as long as the core voltage is not available.
Impact: No Impact, improve Power sequencing
#7 JTAG time constraint
Type: Enhancement
Reason: Signal propagtion constraints to improve JTAG on high traffic
Impact: No Impact, improve JTAG connection
#8 JTAG drive line adjustment
Type: Enhancement
Reason: Driver constraints to improve JTAG on high traffic
Impact: No Impact, improve JTAG connection
#9 Bugfix I2C to GPIO module (I2C_to_GPIO.v)
Type: Bugfix
Reason: Communicate with GPIO subsystem via I2C was not possible.
Impact: Reading and writing data from/to CPLD internal registers via I2C bus works correctly.
#10 Changed Firmware Identifier to REV06
Type: Update
Reason: Show firmware revision with Trenz FSBL.
Impact: None. Actual firmware revision is shown.
More information about System Controller can be found here: TE0720 System Controller.
Method of Identification
All TE0720-03 SoMs noted in the column replacement are with REV06 CPLD firmware.
