You do not need a debugger by the way. The exe is not compressed so you can directly edit it with an hex editor like HxD. 1 - Open EasyPower.exe with an hex editor and look for 0F BE 55 0C (there is only one occurence) 2 - Just before that occurence, replace 0F 84 A4 00 00 00 by 0F 85 A4 00 00 00 3 - Flash the firmware using the new "no check version" of EasyPower you just created --- End quote --- Although more universal that method is riskier since you can flash any FW... untested and/or improper versions also... |

There is a new bug introduced in V1.01.01.02.07R2 firmware and not present in V1.01.01.02.05 where the IP address is not saved correctly. The patch files below corrects this until a full firmware version is released. Note Remove the txt file extension and install the ADS file in the normal way. |

Hopefully it is alright to dredge up an old topic. I wanted to save someone some time and/or heartache. I purchased a SPD3303X-E that arrived with hardware version V6.1 and software version V1.01.01.03.10. I didn't pay too much attention to this :palm: and tried tv84's procedure from the original link in this thread. EasyPower warned me that the firmware did not match, which I should have heeded but am too stupid to quit. I performed the EasyPower hex edit and forced the firmware update and was met with a dead unit. :-BROKE During my panic searching and self-loathing, I couldn't find any recovery instructions. I figured Siglent had some sort of bootloader or firmware update methodology, and held all the buttons while powering it up. Found that holding the adjust knob in while powering on boots to the firmware load screen, huzzah! Firmware Recovery Steps (Hardware V6.1) * Download SPD3303X-E V1.01.01.03.10 ADS from Siglent * Power off * Hold adjust knob in * Power on. Device should boot in firmware mode. * Start EasyPower -> Version -> Upgrade * Choose firmware mode and select the SPD3303X-E V1.01.01.03.10 firmware* *Note: I used the hex-edited EasyPower exe for this, but should work without it While researching, I found that hardware V6.1 was incompatible with the previous (V1.01.01.02.yy) versions of the firmware, which was likely causing the issue. After getting through all that, I was able to send the SDS3303X OS using the hex edited EasyPower. Doing this removed my cal coefficients, so I calibrated the unit using https://www.eevblog.com/forum/testgear/siglent-sds3303x(-e)-calibration-fw1-01-01-02-07r2-best-practice/ and it's working like a clock! Hope this helps, and thanks to everyone for the great tools and documentation. |

Glad you succeed! My 3303X-E will just boot into the firmware upgrade state after I directly upload the firmware of 3303X into it using the modified easypower.exe. Did I miss something? -edit: I didn't read the Release Notes first. It stated that: "B. < V6.1 hardware version of SPD3303X/X-E do not support upgrading to this version (SPD3303X_V1.01.01.03.10.ADS)". The result was the PSU will boot into the firmware update screen after reboot. |
