We purchased a used PV system as a backup. Our current PV systems are running on Firmware version 3.30, while the spare system has version 3.13. We wanted to upgrade the firmware to 3.30 for better compatibility. When attempting to upgrade, we found that only version 4.xx was available. We attempted the upgrade in hopes of standardizing on version 4.xx, but it failed and now the spare system has a corrupt system, displaying error 74. Subsequent attempts no longer result in self-checking, only showing verification/autotest errors. I need to explore options to fix this issue. I believe PB 3.20 and 3.40 have older firmware versions, but I need to access the configuration menu again. We initially downloaded via RS232 - what other options are available using a CF card?
Encountering Error 40, also known as "No executable code to run after boot," can be frustrating. According to the TechConnect knowledgebase, this error indicates a firmware issue. To resolve this, refer to the PVFIRMWARE folder in the PanelBuilder 32 installation files for the necessary firmware files and instructions. Similarly, Error 74 may not be listed in the user manual, but a tech note on TechConnect sheds light on it. This issue arises when trying to use firmware v4.xx on a panel with boot code less than 1.06. Unfortunately, the only solution provided is to send the device in for repair. It's disappointing news, but addressing these errors promptly is crucial to prevent further complications.
Do you know where I can find an older version of the FW file m90kdhp.fmw on CD, specifically version 4.20 or earlier? If so, please let me know.
If you are experiencing issues, you may require firmware versions prior to 4.00.
If you are looking for a copy of Panelbuilder32 version 3.20 with Firmware 3.30, I recommend searching online for a reliable source to download it from. Once you have obtained the software, proceed with reinstalling the firmware as needed.
Hello everyone, I've been struggling to locate a Panelbuilder 32 CD with version 3.20 or 3.40 - version 3.80 could also be compatible. I am in need of a firmware file that is 4.20 or lower in order to attempt to revive my Panelview 900. I tried using a CF card with firmware file 4.41, but encountered a new error 25 (possible incompatible file?) after previously experiencing error 40. Can anyone suggest where I can find older versions of Panelbuilder 32?
I'm sorry to hear about the issue you're experiencing! Firmware mismatches can indeed be a pain. Based on your description, it appears you might've tried jumping too many versions causing a break in process. This happens when certain framework dependencies become incompatible from one version to the next. My first recommendation would be trying to progressively upgrade, if you can find intermediate firmware versions like 3.40 and then moving to 4.xx. Alternatively, having the CF card on hand gives us some options. You could try loading an older, compatible firmware version onto the CF card and then integrate it into the system. This might bypass the corruption issues caused by the incompatible direct update. If you are familiar with data recovery utilities, there might be chances to rescue your system that way as well. Lastly, if you have access to tech support from the PV system manufacturer, it might be in your best interest to contact them for further direction. Good luck, and keep us posted!
Sorry to hear about your predicament with the PV system firmware upgrade. In situations like this, I'd first suggest trying to obtain the original 3.30 firmware, to try and restore the system to the previous stable state. Check with the manufacturer or online platforms for old firmware versions. You could also consult this with an expert in the field if you have such a contact. If RS232 failed, trying another communication route, such as using a Compact Flash (CF) card, might be worth a shot. Make sure to format the CF card correctly before loading the firmware to minimize any potential issues.
Firstly, sorry to hear about your predicament. A corrupt system is frustrating especially when you are keen on compatibility and standardization. Given the error you're seeing, you might have a hardware failure, Firmware version issue or a flash memory error. To address this, you could try re-flashing the system using a CF card. Many modern systems, and I believe yours as well, support reflashing via CF cards. This generally involves downloading the appropriate firmware onto the card and then inserting it into your system. However, you need to take utmost care while doing this as a wrong step could turn the system unbootable. If the problem persists post-reflashing, you might want to consider seeking professional assistance or reach out to the system's manufacturer.
It sounds like a frustrating situation with your spare PV system! If you're looking to restore it, have you tried using a CF card to boot from a known good firmware version? Some systems allow you to load the firmware directly from the card if you configure it properly. You can usually find guides on how to format and structure the CF card for this purpose. Also, check if there's a way to perform a hard reset; sometimes that can help clear up stored errors. It might be worth reaching out to the manufacturer's support, too—they could have specific recovery procedures for the error 74 you've encountered. Good luck!
It sounds like you're in quite a bind! Have you tried using a bootable CF card with the specific firmware version you need? Sometimes, you might need to format the card correctly first and make sure the firmware file is named as required by the system. Additionally, if you have access to any service mode or debug options, they might provide a way to recover the system or at least help you get back into the configuration menu. Also, I’d recommend looking for any documentation or forums specific to your PV system model; often, you can find a step-by-step recovery process there. Good luck!
It sounds like a frustrating situation with that firmware upgrade! If your spare system is stuck with error 74 and isn't self-checking anymore, you might want to try accessing the original firmware files if you have them saved. An option with the CF card would be to create a bootable CF with the older firmware versions — make sure to format the CF properly and follow the specific instructions for booting from it. Sometimes, connecting the system to a computer via RS232 and using terminal software can help you recover the configuration menu, so it’s worth exploring that route as well. Good luck, and I hope you can get that backup system up and running again!
