Does anyone know of a file I can modify to add a boot-time invocation of telnetd, that will survive a firmware update on an SDS2000X from V1.3.9R6 to V1.5.2R3?
I'd like to move to the new firmware, but rely on the telnet interface for various mods. Like monitoring device temps to calibrate a PWM fan replacement, maintain the clock on localtime with ntpd, etc.
V1.5.2R3 is mainly housekeeping of minor production changes whereas V1.5.2R1 has fixes and enhancements for numerous issues:
Measurement enhancement - Added setup/hold time: tsu@R, tsu@F, th@R, th@F
Optimized UI
Added SCPI commands for Measure Cursors and clearing measure items in Simple mode
Supported LXI (only with the Uboot-OS Version 5.4)
Supported time zone setting
Fixed several bugs
Webserver doesn’t show instrument UI if the scope reboot with a wireless mouse connected
Incorrect “Recall”icon in the File Manager
Scope freezes with AWG enabled and measure cursor on rise time
IP setting of AWG in Bode Plot not remembered after reboot
Network storage only works for SMB1.0
MEAS:SIMPle:ITEM\sOVSN,ON does not work as expected
Roll time incorrect at 1ks/div and 20kpts
Raw data not consistent in x and sinx/x interpolation modes
Math: Dx parameter of Derivation cannot be increased by universal control
Incorrect FFT sample rate
