A common mistake is to use a constant current load (an active load) on the output of a hotswap and expect normal behavior. This is usually a problem for several reasons: 1) The loads typicaly act like a short when voltage is first applied until their…
Hi Sal,
Both the BSL_INVOKE and NRST signals are connected to GPIO lines on the SoM, so I had been manipulating their levels using the Linux 'gpioset' command from the SoM. I had been asserting BSL_INVOKE (i.e., set high) for 30 seconds in one shell…
Hi James,
Yes MSP430F5 requires flashing for USB2MDIO. One way to flash the MSP430 is using Uniflash with the flash image file below:
2437.msp430-usb-to-mdio-universal-v3.04.txt
Here is a guide for bringing up USB2MDIO with uniflash: 5141.How to…
Hi Zeynep,
I believe this is coming from a timing issue related to the sector erase in your flash kernel. I have attached a version that uses bank erase to erase all of flash before downloading and programming the data, can you try this?

HI，
The recording now sounds free of background noise. Please see the attached "cap.wav". However, the recording gain is very low. When AGC is enabled, noise still persists. Attached: "cap-onAGC.wav".

Hello,
If using the launchpad, please ensure that the MSP is flashed with FW specific to USB2MDIO. In addition, MDC is actually P4.1 while MDIO is P4.2. The MSP will provide the MDC as needed, and will not be free-running.
I have attached a .ppt and…
Hi JH,
Here is the MSP430 binary file used on this EVM to interface with the DP83869: DP83869EVM-Driver.txt
Let me know if you have any questions.

Hi Divyansh,
drivers/gpu/drm/tidss/tidss_irq.c code seems bit different #L62 to 64 is
spin_lock(&tidss->irq_lock);
irqstatus = dispc_read_and_clear_irqstatus(tidss->dispc);
spin_unlock(&tidss->irq_lock);

Hello,
It looks like the device isn't executing the kernel (the program counter is in the boot ROM), which is why loading the symbols failed to reveal anything.
I also successfully executed the SCI boot flow on my F28003x LaunchPad, can you please…
