In general I was looking in the archives here from a search of Broadcom bootloaders, CFE, etc. I browsed over a post from Mr. Feret.
Could anyone enlighten me if they know if sat. receiver SOC's come with a CFE or bootloader already flashed? Or if JTAG or other methods of getting a basic method to install an image could be learned?
Briefly. I have been given 2 Edision Os Mio4k+ receivers. Both experience no HDMI because the TVS were zapped and shorted the chip to HDMI pinout grounds.
But on both the webif works and streaming is possible over LAN.
My HDMI port tester showed dead data lines after removing the shorted transient suppressors. And the chips that were running quite warm cooled down considerably.
As you may suspect. I do have an "adequate" SMD repair station with proper equipment to perform repairs.
I have tried contacting Broadcom directly. I have established an account. Dealing with them is like root canal. On second thought, root canal would be more pleasurable.
They are really good at draging their knuckles.
The IC in question is the Broadcom BCM72604. And I've searched a bit to investigate Broadband Studio and have downloaded a copy (old one) to see how to navigate it.
I have sourced replacements from Ali Express and the price isn't too bad. I've extracted one IC from one receiver and prepped it for a new one.
I am reluctant to do any more until I find out if I need JTAG the firmware as a backup to flash a new chip once installed.
I'm very eager to learn the methods. If a CFE, bootloader were already programmed in the new chips. Then flashing an EMMC from USB would seem like a breeze.
So far dealing with Broadcom is getting really stretched out. And I see others appear to be quite adept at STB chips like these.
Anyone? Hoping for some positive input as the receivers are nice. Edision considers them throw-aways if the go defective.
Am I able to lift the firmware needed to flash a new chip? Do they come with a bootloader of some sorts burned in them already?
Sorry for the "book". I like to save a bit of back and forth when I can.
Thanks!
