About saroo, for newbies, how to get debug and program saroo

[luisredo]

Hello everyone, I am writing to you to obtain a little information, how could I test my saroo, I think it is bricked and I would like to know how to check the FPGA and the stm32, I would also like to know If there is the possibility of obtaining debug to see if saroo starts well, mounts the SD drive and obtains information from the console.

Thank you very much and greetings. Sorry for my English sponsored by Google translate.

Connect a USB-Serial dongle to SAROO(1Mbps), you will see MCU infomation. The led on your board is lighting, so they are works fine, I think. What the last version of your board?

I have version 1.32F, what I don't know is the baudrate(1Mbps) or what the RX and TX pins are. In another post I read things that clarified a little more for me, such as being able to flash the nand without having to use quartus, putting the bin directly into the FPGA flash. Can the stm32 be programmed with a st-link? I saw you commented that you used jlink, I'm not sure if it's the same thing.

I connect the serial USB to the saroo and I get this through the console.

There has error msg:

Please check your SD Card.

"Can the stm32 be programmed with a st-link? " Yes. Any xLink can be use.

In other memories I get others but in SDFS it always shows 000000

hablando con colegas en telegram, les comparti el codigo, y dicen que es raro que detecte el bootrom file en esa direccion de memoria Found Saturn bootrom file. Size 00060000, pero que no monte el SDFS como dices.
