First off, my setup. IDE/compiler: IAR EW430 6.50.1 Programmer: MSP-FET (Jtag speed set to Medium in IAR, also have tried with Fast) Micro: MSP430FR5969 SD Card: Kingston microSD 16GB SDHC as well as 64GB and 1GB cards I am trying to integrate Chan's FatFS on the MSP430FR5969 designed into a custom PCB. I am able to initialize the SD card (put it into Idle State, then put it into run mode). The issue I am having is when I have the MSP-FET connected, I have three problems: It takes about 1.3 seconds for the SD card to go into run mode (it should take hundreds of milliseconds) The data received from the SD Card indicates a SDSC, when the card is actually an SDHC Once initialized, the SD Card returns an invalid command to a read block request I post this here because when I remove the MSP-FET , the SD card: Initializes in 0.14 seconds Reports back as SDHC Allows Block Request commands I'm wondering if this has to do with clocking from the MSP-FET , or some setting that I can change (hopefully). It's going to be difficult to debug from here out if I have to disconnect my debug tool every time. Thanks for the help in advance! -MC
